Why Do Dogs Lick and Chew on Wounds?

If your dog is chewing on himself, on a hot spot, or other types of wounds, you may be dealing with two problems: the wound itself and, on top of that, your dog repeatedly pestering it. The problem may be challenging and quite troublesome for the simple fact that the wound is never given an opportunity to heal. But why do dogs seem to enjoy so much chewing on themselves?

When your dog chews on himself, it is very important to understand the source of the wound. Was the wound caused by something (i.e., a scrape, scratch or bug bite), or was it self-inflicted?

Self-Inflicted vs. External Causes

The difference between the two is very important. If your dog is causing self-inflicted wounds, the treatment plan will require a careful assessment as to why the dog is doing that. Self-inflicted wounds in dogs are often seen in cases of separation anxiety, obsessive-compulsive disorders, boredom, stress, and frustration. In these cases, the dog chews simply because it helps relieve stress, anxiety, or boredom in a similar fashion as some nervous people resort to nail-biting.

When it comes to these types of problems, the underlying trigger will need to be addressed. Yes, you can stop a dog from chewing, but the dog will still feel the need to do so and will persevere if changes in his lifestyle are not made.

If the wound is caused by a scratch, hot spot, bug bite, or another type of wound, and is not self-inflicted, consider having the wound assessed by your veterinarian and then try some of the solutions below to stop your dog from biting the area. In these cases, the dog tends to lick and chew on the wound because it hurts and the dog is trying to get some relief. Dogs have a natural inclination to lick their wounds, and this instinct is not to be blamed.

Why Do Dogs Lick Their Wounds?

According to Patty Khuly, a practicing veterinarian based in Miami, Florida, if humans lacked opposable thumbs, and thus were unable to access disinfectants, they would possibly lick their injuries too. Also, it appears that the saliva of a dog contains several beneficial compounds, meant to destroy the cell walls of gram-positive bacteria, promote wound healing, decrease pain, and inhibit bacterial growth! All these marvelous enzymes and compounds, along with their benefits, are listed in her article on Vetstreet.

Potential Consequences

However, while a little licking may be beneficial, dogs seem to overdo it and even get obsessive about it. Too much licking along with the abrasive effect of the teeth should the dog nibble on the wound too, may lead to problems.

Also, a wound kept moist by constant licking will create the best environment for bacteria to set in and prevents the wound from healing. Soon, a tiny wound could become a bloody mess and may develop into a hard-to-heal acral lick granuloma. A wound that would heal in a few days, instead may last for weeks and even months in severe cases. How to stop the vicious cycle? There are several options to consider, including these 5.

Option 1: Invest in a Elizabethan Collar

One of the best ways comes straight from your veterinarian clinic or favorite pet store. As a former animal hospital assistant, I have helped countless dog owners fit those lamp-shade collars to protect a dog from pestering its stitches. Many dogs found the collar humiliating and many owners found it funny. Truth is; it is effective and can really help prevent your dog from repeatedly pestering the wound. However, some smart/persistent dogs may figure a way to get it off (they push it against something) or may find a way to chew part of it.

If you need a temporary Elizabeth collar, you may want to read how to make a homemade Elizabethan collar using a bucket, an ice-cream container or some cardboard. See how I made a temporary e-collar using a Finding Nemo placemat. This one lasted one night; just enough to get my boy through before purchasing an authentic one at the vet's office the next day!

Option 2: Invest in a Bottle of Bitter Yuk!

Not all dogs are tolerant of an Elizabethan Collar and some manage to find a way to get it off. If you need to leave your dog home alone and you really need to stop your dog from pestering the wound, you can invest in a bottle of Bitter Yuk.

This is what I have been using on my dog Kaiser which every summer gets an annoying hot spot which lasts longer than it's supposed to because the moment I leave (as soon as he hears the engine), he starts chewing on it—I know because I recorded his behavior.

The taste is pretty awful, I know because I accidentally sprayed a bit on my lip by accident and it is three days and I still taste it if I lick my lip. Kaiser has left his wound alone so far; I do see him thinking about it though, turning his head and then changing his mind as if he is reminding himself of the terrible taste. The hot spot seems like it is finally recovering too. I always shave hot spots to keep them dry and to allow them to heal more promptly.

Option 3: Use Boxers or a T-Shirt

At times, dog owners were calling our veterinarian hospital asking for desperate tips to stop a dog from licking its wounds. In such cases, if the wound or stitches was near back legs, rump, tail, or genital area, and the dog could not be seen that same day, we recommended letting the dog wear a pair of men's boxers. If the wound was in the abdominal or chest area, wearing a t-shirt was another option. Of course, an eye must be kept on the dog since many dogs are pretty good in removing these items, but the boxers or shirts made the task more difficult.

Option 4: Train "Leave It"

The leave it command, which every dog should know, can be expanded to training a dog to leave its wounds alone. Of course, this command will only work when you are around. The main disadvantage is the fact that your dog starts associating "leave it" with your presence, and therefore, the moment you turn your back, leave the room or leave the home, your dog will start pestering the wound. Make sure when you ask "leave it" to give a stuffed Kong or a toy to keep your dog occupied and keep his mind off the wound.

Option 5: Ask Your Vet for Itch Relief Products

Many times, the poor dog is licking/chewing the wound because his skin is itchy. In such a case, the dog can be helped with some products meant to relieve itching. Your vet may prescribe a product such as diphenhydramine (plain Benadryl), a cortisone-based spray, medicated shampoo or even steroids for severe cases. For natural remedies, Dr. Mark1961 has a helpful article: Natural Dog Health: Allergies.

As seen, there may potential solutions to your problem. As much as the problem is frustrating, you can manage your dog with close supervision when you are around, and the aid of helpful tools to deter unwanted licking and chewing of the wound when you are away.

I have 2 dobermanns and an American Staffy. My female dobermann got attacked by a cat and has a wound above her eye, beside her eyebrow, that my other 2 dogs have been licking at. I have tried bandaging it but she either pulls them off or refuses to move. A cone does nothing because it's other dogs doing the licking. Is bitter yuk safe to use that close to the eye? If not, what can I safely use to stop my other dogs from licking her wound?

I am so sorry to hear about your dog! What a terrible ordeal to go through. Your dog is at serious risk for systemic infection. You can try to apply for Care Credit and see if that can help. Explain your situation as well to several shelters around you.

My dog hurt her leg a few days ago. I t swelled up terribly bad and she started licking at it above her paw. She licked it and chewed ot raw. I put a collar on her and the cone of shame. Somehow during the night she got it off and we heard her scream and not stop about 5 in the morning. We ran to her and she has chewed her leg completely in half. Bone is sticking out and she chewed that in half as well. She was attacking her leg and the scream we heard was her pain and anger at hurting and attacking more. I got her calmed down and pulled her head away from her now destroyed lower leg. I called vets, animal hospitals and finally the spca here because they have a vet and a surgery clinic for k9's. Get this. ALL REFUSED TO HELP ME. Even the spca. Because I am a disabled veteran and get money one time a month, and cannot get th pet insurance because i got in a hole when I couldnt work any more, I could not pay in advance but could pay on the first. they all basically said tuff luck. figure something out yourself. What the hell has happened to vets when they choose money over an animal in pain? I supported the spca for years, i shop at their giant thrift store that makes them on average a hundred thousand dollars A MONTH. still they refuse to help.Now I am stuck and my poor dog is stuck. What do I do? Put her down? she is just 2 years old and a twin sister. she is like my kids to us. right now she is sedated luckily from a past injury med. but that is gone as well now...
