There Are Good Pet Foods Out There

For dog owners, dog food is a confusing world of information (some of it bad) and advice (much of it also bad) with the internet, advertising, and advice from well-meaning friends who often really don’t know much.

In a career that spans three decades of dealing with pet owners and their pet food choices, I’ve never seen it this confusing. Pet owners are overwhelmed by all the choices, and don't know who to believe when gathering information.

Surf the right sites (I like the ones that end in .edu or .gov), and you can get some great information. But there’s also a lot of misleading and inaccurate information out there. Some misinformation even comes from sources you’d expect to be able to trust.

For example, say a manufacturer makes a very good holistic pet food. In their advertising they send you to their website for a food comparison. The problem is that they compare themselves to lower-quality foods so, sure, they look great.

If they compared themselves to any of the other holistic brands, it would be a wash. So, there’s a site you’d expect to trust, but they spin the information to their advantage. All the data they present is accurate, but they’re comparing apples to oranges.

In this pet food primer, I want to help you separate the science from the myths and marketing so that you can make intelligent, informed food choices. To begin with, let’s bust a few myths about pet food.

Myth # 1: "The Great Taste Dogs Love"

Dogs lack enough receptor cells on their tongues to discern tastes. On that aisle-runner-tongue of theirs are about 1700 taste receptors. By comparison, on our stubby little tongue are almost 10,000 taste receptors.

When you offer a treat to a dog, he'll sniff it and make the decision to accept or reject it based on its aroma. Sometimes they'll reject food or treats based on how they feel in the mouth, which comes under the heading of texture.

Thus, palatability is driven by aroma and texture. If it passes the sniff test, it’s going down, unless it doesn’t feel right in their mouth. Think about it.

When they accept food or a treat, it's a chomp and a swallow. They never let food dissolve in their mouth, so as to enjoy the flavor, and if they could taste would finish the sentence!

Cats, by the way, have an even poorer sense of taste, and generally favor things acidic. They have fewer than 500 taste receptors. They’re unable to detect sweet because, researchers discovered, they lack the "sweet gene," a protein that would give them a “sweet tooth.”

So that pretty much blows the age-old theory that dogs and cats drink anti-freeze because it tastes sweet. Cats can’t taste sweet and dogs practically can’t taste anything at all. Manufacturers exploit the fact that flavor is huge to us, the decision makers, and it usually works.

When referring to a food's appeal to a dog, the word "taste" fits better than the word "smell," so it's widely used in advertising and even by vets and nutritionists, who know better.

Professionals refer to palatability. The word taste is just easier for pet owners to wrap their minds around.

Pet food manufacturers employ ingredients known as palatants, whose only job is to optimize the animal's response to the food. Sometimes palatants are used in concert with fats, sometimes alone.

About 80% of manufacturers spray the palatants onto the surface of the food, the rest bake them in.

You'll see palatants listed on the ingredient panel of your pet food as animal digest or natural flavors. Animal digest is a broth of slaughterhouse leftovers that's hydrolyzed and sprayed onto the food. It's not a consistent formulation. Natural flavors are scientifically formulated and consistent from batch to batch.

Myth # 2: Meal Is a Low-End Ingredient

Chicken (muscle meat with its water content intact) is about 70% water. It's pulverized into slurry and sent to the extruder (for cooking and shaping) with its water content intact.

Chicken meal, instead of being pulverized into slurry, is cooked in water until all the water is cooked off. The meat is then baked until it crumbles into a protein dense powder. It boasts up to three times the protein as chicken.

If you have a pound of chicken in your left hand and a pound of chicken meal in your right hand, your right hand is holding a lot more protein, as meals contain up to 300% more protein than the raw meat.

When a named meat is listed first on the ingredient panel, look for a named meat meal to be next. Some foods use, in descending order of quality, chicken meal, chicken by-product meal, poultry by-product meal, meat and bone meal, or add the supporting protein a few ingredients deeper in the ingredient panel.

Because chicken (which is water dense) is the first ingredient, it requires a back up protein to bring that nutrient to the levels stated in the package’s guaranteed analysis. Of those that list chicken (or any species-specific meat) first, the better foods use species specific meal as the second ingredient.

Think of it another way: your grocer’s meat department takes a half-pound of sirloin steak and a half-pound of stew beef, grinds them into a pound of hamburger and charges you $10.99.

The meat is satisfactory nutritionally, but it’s $6.99 meat, not $10.99. So, having chicken and chicken by-product meal as your pet food’s protein is good quality protein, but it’s sort of like getting chuck at sirloin prices.

When chicken meal is listed first, they don’t need to back it up because its nutrient density is sufficient as a stand-alone protein. The exception would be holistic pet foods, which inherently contain multiple protein sources and often use the meat, not the meal. The additional meats can make up the protein difference that meal would provide.

Multiple protein sources are a blessing and a curse. If the dog develops an allergy, and the vet thinks it's a food allergy (which is almost always to a protein), the matter gets more complicated. The elimination diets can take months and months to complete.

Bottom line is that, if a pound of chicken goes into the extruder, it will cook down to around four or five ounces. If a pound of chicken meal goes into the extruder it will cook down to around 13 ounces.

Myth # 3: Beet Pulp Stains the Coat Red

Beet pulp, a by-product of the processing of sugar beets, is actually black and is an appropriate fiber source in pet food. It also has prebiotic qualities.

Porphyrin, a compound found in tears and saliva, reacts to UV light and can cause staining below the eyes and around the mouth of dogs. If he frequently licks his paws, you'll see staining on his paws as well.

Myth # 4 A Certain Brand Is the Best Dog Food

I hear a lot of pet owners proclaim that "X Brand" is the best food. Not true. There's no such thing as "the best" food. The truth is, within genres, the brands are quite similar in formulation and nutritional value, and will nourish your pet equally.

Now that we’ve given you something to argue with your friends about, let’s look at pet foods from another angle.

Appealing to the Emotions of Pet Owners

Most pet owners make decisions regarding their pets based more on emotion than science. Manufacturers of pet products are very much aware of this (they call it the humanization of pets) and most always aim their advertising messages at the heart, not the brain.

To illustrate how huge a factor marketing is, consider that there are only four AAFCO standardized formulations of dog/cat food. AAFCO stands for the Association of American Feed Control Officials, an association made up of local, state and federal agencies mandated to regulate the sale and distribution of animal feeds and drug remedies.

The AAFCO nutrition statement can be found near the ingredient panel on most pet food containers and would indicate that the food "was formulated to meet" or that "animal feeding trials using AAFCO procedures substantiate that" the food provides complete and balanced nutrition for one of the following life stages:

Gestation and lactation, often listed as growth and reproduction. This is puppy or kitten food.

Large breed puppy, is AAFCO's definition of a dog that will be 70 pounds or more at maturity.

Maintenance, is adult dog or cat food.

All life stages, means that the food is complete and balanced for dogs and cats from weaning through adulthood.

Everything else, such as Large Breed Adult, Senior, Small Breed, Limited Ingredient, Weight Control, etc. is at the discretion of the manufacturer

That can lead to some confusion among consumers. One manufacturer, for example, may consider senior dogs to be couch potatoes while another may recognize that many senior dogs are still quite active. Each can formulate a "senior" food accordingly. You'll have two "senior" foods that are very different, nutritionally.

There are, however, generally accepted industry descriptions for different genres of foods, such as grocery, super premium, holistic, organic, and grain-free. Keep in mind that there are no legal or regulatory definitions of these types of food. Let’s look at each genre individually.

Grocery Brands

Generally, a grocery brand’s ingredient panel starts off with corn and continues with ingredients commonly considered to be inferior (such as beef tallow, wheat, soy, sorghum, artificial colors and chemical preservatives such as BHT or BHA), or unspecified ingredients (such as poultry by-products, meat and bone meal, animal digest, animal fat),

Below is an ingredient panel that is typical of a grocery brand dog food. Most contain the same, or similar, ingredients and not usually in the same order.

Dogs and cats have no dietary requirement for carbohydrates. Cats (and ferrets) are, in fact, obligate carnivores because of their taurine requirement. In the wild, cats and dogs would live almost exclusively on animal protein and animal fat.

However the manufacturing process of dry dog and cat foods does require carbohydrates. Without them, you'd end up opening a bag of crumbs. They're the "glue" that holds the kibble together.

In low end foods you'll see wheat, corn, soy, sorghum and other carbs that can be problematic in that they can contribute to skin and digestive issues. The high end foods use carbs such as oatmeal, rice, barley and rye.

They're not known to be problematic and can actually have some value as supplements for skin, coat and digestion. The grain-free foods use carbs such as peas, potatoes and tapioca.

This Ingredient Panel Is From One of the Grocery Brands

The Pluses and Minuses of Each Genre

Advantages Of Feeding Grocery Brands: You can conveniently pick them up when shopping for your own needs. You thought I was going to say “economy” huh? Nuh-unh.

For every cup of a grocery brand you feed, you’d generally feed about a heaping half cup of a super premium and a rounded half cup of a holistic food.

Disadvantages: Dogs on grocery brands often have drier, itchier skin, shed more, are more susceptible to body odor and doggie breath, produce larger volumes of soft stool, will clear a room with their gas, and their various organs and systems don’t get the level of support they’d get from better quality ingredients.

Super Premium Brands

Super premiums are meat-based and the better ones use the meal form of protein such as chicken meal, lamb meal, etc. as the first ingredient.

Other high end ingredients could include chicken fat, flaxseed, rice, beet pulp, mixed tocopherols and chelated minerals (look for the word proteinate or chelate after the minerals). Chelated is pronounced kee’-layted, by the way

Chelation serves to maximize and equalize the absorption of minerals. When the dog’s gut breaks down the minerals, they can build up a positive or negative electrical charge, bind to anything else inorganic and be excreted in the stool.

In chelation, the manufacturer pre-binds the minerals, either to proteins or carbohydrates, rendering them electrically neutral. They don’t build up that electrical charge and therefore become more bioavailable.

Advantages Of Feeding Super Premiums: Because of the higher levels of better quality essential fatty acids, the animal’s skin is more supple, holding the coat better and resulting in less shedding.

Stools are smaller and generally better formed, gas, body odor and doggie breath are pretty much eliminated, and the animal enjoys generally better health.

Disadvantages: Cost a little more than grocery brands and may not be as conveniently available. Most can be purchased online, too.

Holistic Brands

Since there are no legal or regulatory standards for "holistic" foods, we can't define them for you. But, there are some common threads that run through the brands that consider themselves holistic.

Holistic foods generally have two or more high quality protein sources, probiotics (they read like diseases on the ingredient panel), prebiotics (they support the probiotics while in the bag), botanicals such as blueberries and cranberries (in there for their antioxidant, urinary and cancer-fighting properties), and chelated minerals.

They typically use only whole grain rice, oatmeal, rye and barley for grains, eliminating the harsher grains such as wheat, soy, corn, and sorghum.

Grain-free foods are considered holistic but without the rice, oatmeal, rye and barley. The better ones use the meal form of the protein. If not, they immediately back up the first meat protein with a species-specific meal and are still high-end. Foods labeled organic are certified by an agency such as Oregon Tilth to be around 75 per cent organic.

That means that most of the ingredients were raised or grown without pesticides, chemical fertilizers, hormones or other chemicals.

Maybe it’s just me, but is there a value to an organic meal when the dog washes it down with a few gulps from the toilet bowl, grabs a quick dessert from the cat’s litter box, then plops himself down for a long, leisurely butt lick?

Advantages of Feeding Holistic Brands: The same as feeding super premiums, but bumped up a notch. Nutrients are added that target specific organs or systems, such as glucosamine and chondroitin for joint health or probiotics for digestive health.

DISADVANTAGES: Are significantly more expensive than grocery brands, a little more expensive than super premiums, and generally only found in pet specialty stores and online.

"Complete and Balanced" Isn't a Marketing Term

The value of commercial dog foods is that they are complete and balanced. Complete means that they contain all the nutrients necessary to maintain optimum health; balanced means that those nutrients are in proper proportion to each other.

If they’re not, some dangerous imbalances could occur, such as a calcium-to-phosphorous ratio that’s out of whack.

Making good pet food isn’t simply a matter of collecting a bunch of high quality ingredients and putting them in a bag.

Animal nutrition is a complex and sophisticated specialty with its own degree program, board certification and professional organizations.

The pet food manufacturers do a pretty good job, but as you’ve learned, not all pet foods are created equal.

      Hi Millionaire Tips, nice to meet you. I would choose something that begins with the meat meal of an identified species, ie: chicken meal, lamb meal, etc. Watch for the absence of wheat and soy. I wouldn't object to corn, but not as the first ingredient. Look for chicken fat instead of poultry fat or animal fat.

      Look for chelated minerals. They'll be identified by the words proteinate or chelate after them, such as Zinc Proteinate, Manganese Proteinate, Iron Proteinate, Magnesium Proteinate, Copper Proteinate. Flaxseed is also a good ingredient to watch for.

      Avoid ingredients such as wheat, soy, animal digest, meat and bone meal, poultry fat, animal fat, peanut hulls.

      My favorite to recommend is Pro Pac. It's economical and well formulated, containing many of the good ingredients I've just mentioned. If you want to go grain-free, I'd recommend any of them.

      My favorite is Earthborn because they use the meal form of their proteins, but I'm equally as enthusiastic about Wellness, Merrick Before Grain, and any number of other holistic, grain free foods.

      You'll pay more for grain-free, but feed less, pick up less (stool and hair), and the dog will benefit more from the high end ingredients.

      I hope this has been helpful. Thanks for stopping by and commenting. Regards, Bob

      This is really interesting, as I am still trying to decide the right food for my dog. What's the most economical healthy food for him? Voted up.

      You should be writing comedy, Christine! I love your last line about the female puppy that turned out to be a bitch. lol. The little male that melted your heart must have been a hot dog. groan.

      Once he's used to being in a safe environment and gains the confidence and cockiness they get when exiting puppyhood, I wonder if he'll get a little cranky? I would expect some attitude.

      DrMark1961 is a hubber who knows a lot about the various breeds and we cyberchat quite a bit. I'll ask him what he thinks. I just find that an interesting cross. I doubt if I'd choose that combination if breeding for temperament...unless I owned a small junkyard. Deez are da jokes, folks.

      From one sick mind to another, thanks for stopping by; fun chatting with you. Regards, Bob

      I think it takes a "sick" mind to recognize another. :) His mother was actually the Chihuahua, go figure. He is extremely timid. We got him at 9 months old from my cousin who has been breeding small dogs for over 15 years. I know he wasn't abused but according to my cousin, his sister was a bully. I went there to see another pup that I thought would be a better fit for our family but she turned out to be a bitch and he melted my heart.

      Hi Christine, thanks for stopping by. I'm glad someone finally appreciated the line you referred to in your first sentence. I thought it was a good line, but all it got was crickets.

      I'll bet the honeymoon between the chihuahua and the poodle was an interesting event. I'm curious as to your dog's temperament, since both breeds can show a little orneriness.

      Your food choices have been good, but Diamond has had a few recalls recently, involving some top names, Canidae being one of them. Wellness is another, but I was in contact with an official from Wellpet LLC and they recently opened a new production facility of their own. They had severed the relationship with Diamond, anyway.

      Diamond makes their own brand, Chicken Soup is their brand, and they manufacture for other companies, too, although I don't know how that's working out for them now.

      There are a number of good foods out there, including Flint River, that use human grade ingredients now. If you're in the holistic food genre, it's pretty hard to make a mistake.

      Thanks, again, for stopping by and for the votes. Regards, Bob

      Think about it, if they could taste would finish the sentence! Hysterical!! Great article voted up & more.

      In February I purchased a Chi-Poo (1/2 Chihuahua, 1/2 poodle) I did tons of research and settled on Canidae. I weaned him off the Chicken Soup brand the breeder was feeding him and he was fine. Mid May he started with diarrhea. Over the next month and a half the Vet put him on hamburg & rice diet on three different occasions, the last time with an antibiotic. I searched the web and found Canidae had been recalled in the beginning of May for Salmonella. (Vet had no clue)

      Now I only feed him Flint River brand because it only uses human quality ingredients. We had to put our previous dog to sleep after 13 years. The last thing my kids needed was to lose another pet, especially from something that could be prevented.

      Thanks for stopping by Choxy. I'd have thanked you earlier, but it took me a while to "get' this Approve/Deny thing.

      Thanks for your kind words, Patty.

      You're not alone JayeWisdom. Since the big recall a few years ago, other owners have lost their faith in the commercial foods.

      I take a different view. As large as the recall seemed, it was a tiny percentage of the market. And even after that, industry data suggests that some 96% of the nation's 77 million dogs are on commercial food.

      Pet food is a heavily regulated commodity and since the recall, the standards maintained by many manufacturers exceed what is required by regulations, which became even more strict as a result of the recall.

      I don't find fault with owners who feed home made diets that are created or approved by Board Certified Animal Nutritionists. If your veterinarian approves of the diet you are feeding I would assume that it falls within such approved guidelines.

      I've known owners who base their diet and supplement decisions on recommendations of holistic practitioners who don't have any veterinary nutrition training or credentials, and I think there is some risk to that.

      I've also known it to be the case that, after the novelty of feeding a home made diet wears off, many owners stray from their professional recommendations and substitute ingredients that they believe to be acceptable alternatives. I believe that there is some risk to that, too.

      As you know, preparing a home made diet that is complete and balanced often means shopping for ingredients that may not be readily available, that are available in sizes too great or too small for what the recipe calls for, some that are pretty expensive, and others that may not be for the squeamish to keep in the fridge.

      Those of you who stick with it, and "by the book," are providing excellent nutrition for your pets and I salute you. It's a lot of work but I'm sure it is, indeed, a labor of love.

      I'll visit your hub on the subject. Thanks for commenting.

      I no longer trust ANY commercial dog foods, so I've been preparing my dog's food at home each week in my own kitchen. She thrives on it, which is the gauge by which I measure its success. (Her vet approves of what I feed her, especially since she has some food allergies and a tendency toward pancreatitis, which means she must be on a low-fat diet.) I published a hub about how I make her dog food...if you're interested.

      To: Choxy

      Blue Buffalo is a high quality food and I see no reason to switch. At that level, you can't make a mistake. The differences between the various brands of holistic foods are insignificant...more marketing than science.

      To: DrMark

      Here's a likely reliable link:

      I should have inserted the word "enough" between "lack" and "receptor." I do, however, stand by my statement that dogs "practically can't taste anything at all."

      In instances like this where the true condition is uncertain, I look at the reality check. We know that dogs have about 1/6 the receptor cells that we do, and that they're mostly clustered around the tip of the tongue.

      The reality check shows that, when you offer a treat to a dog, it never tests it with the tip of the tongue. It simply takes a quick whiff and either rejects it or wolfs it down, often barely chewing it.

      It is said that they can detect sweet, salty, etc. but it isn't known how well they can detect those, or if there is a preference. It just seems to me that if dogs had more than a primitive sense of taste, they would display preferences, and that if they had preferences they'd be a little more selective about what they take into their mouths.

      As you well know, dogs aren't particularly discriminating about what they ingest. I believe that if they could taste what they take into their mouths, they wouldn't eat much of the nasty stuff they do eat.

      Dogs regularly engage in pica, and that seems to be driven by their sense of smell, which is awesome. When we walk by a pizza parlor, we smell pizza. Dogs smell yeast, tomatoes, oregano, etc.

      That's why a trained dog can be taken to an airport baggage carousel and from among scores of bags filled with soiled underwear and outerwear, toiletries, cosmetics and souvenirs, it can pick out a baggie containing cocaine.

      The knowledge of exactly how well dogs can taste will continue to elude us until we can actually communicate with them, and I think my toddler grandson will see that day. Thanks for following.

      Do you have any scientific evidence to back up the claim that dogs have no tastes receptors? I have read otherwise.

      Also, I think dogs may be able to smell sweetness, which is why they are attracted to antifreeze. All we know is that they have a powerful sense of smell, we do not understand exactly what they are smelling.

      Thank you for the article. I included myself in your "follower" category.
