My Dog Has a Lump—What Is It?
Every day, somebody across the globe will discover a lump on their dog and ask themselves or people around them, "My dog has a lump, what can it be?" We may start wondering whether the dog was bitten by a bug or whether it's just temporary swelling that may go away.
Some owners may even ignore the lump, thinking it is just something minor, especially if it's small in size. Others may take a "wait and see" approach, which means they'll keep an eye on it and see the vet only if it gets bigger. Finally, some will see the vet the next day because they are concerned. Different people have different approaches in dealing with the appearance of a lump on their dogs, but who is ultimately right?
There is really no correct approach in these cases, as it highly depends on what the lump ultimately turns out to be. The owner who ignores it may be lucky if it turns out to just be a local reaction to a bug bite. The owner who waits may be lucky if the lump just stays the same size over the next weeks and months. The owner who sees the vet the next day may be lucky he did so since he caught a malignant growth in its earliest stages, but things don't always turn out this way.
Learn why all lumps, regardless of appearance, should be seen by your vet. In this article, we will take a look at some answers to the common question: "My dog has a lump; what can it be?"
My Dog Has a Lump—What Could it Be?
So you found the lump on your dog, and now you are skimming through websites and the entire blogosphere, trying to figure out what it could be. In this article, I will be doing you a big favor and saving you a great amount of time. The truth is, you may never find out. This may burst the bubble of many of those hoping for a straight answer and a possible Internet diagnosis courtesy of Mr. Google.
There are many reasons why you cannot know exactly what that lump is, unless you saw a bug bite your dog and you are 100 percent sure that's why your dog got that temporary local irritation. But then again, if you knew, you wouldn't be searching the web, would you?
Following are some reasons why you won't ever be 100 percent sure what a lump is until you see your vet and why it's not safe making assumptions about what it is when it comes to lumps. Of course, it doesn't hurt to do some harmless research just to look at possibilities and get an idea what to possibly expect, but you should never assume what you read or see can offer a diagnosis and can be used as a substitute for veterinary advice!
Your Vet Won't Likely Know Either!
Countless owners bring their dogs to the vet and ask their vet "my dog got this lump, do you know what it is?" They are often hopeful their vet says it's nothing and sends them home. They are then surprised when the vet shrugs their shoulders and confesses that they doesn't have a clue what type of lump it is exactly.
You may think, without saying it out loud: "What do you mean you don't know? You're the vet, you should know!" Please, don't take your frustration out on your vet; they are being totally honest, and you should thank them for their integrity in not making assumptions.
Veterinarian oncologist Susan Ettinger says it crystal clear.
"No one—not a vet, not an oncologist, and not you—can tell what a lump is just by feeling. Not even the most experienced veterinarian can look at or feel a mass and know if it is cancer or not."
So if your vet, who has gone to vet school for many years to get their degree and license, doesn't know what the lump is, how can somebody on the Internet tell you exactly what it is? How can you figure it out? You may wonder at this point: Why is that? Why can't your vet over the years learn to recognize what kind of lump your dog has? Read on to learn more about why lumps are so difficult to diagnose.
Some lumps may be tricky to identify. In some cases, a fine needle aspiration may come back inconclusive or suspicious, and a biopsy may be needed or the vet may suggest simply removing the lump and sending the whole thing to pathology.

Why You Should Always Get Your Dog's Lump Checked Out
You may at times feel tempted to wait to have that lump checked out because it's small, looks innocent, and isn't growing much. Perhaps even your vet suggested you do so. This is a scary trend that pet owners should be aware of.
There have been cases where vets have told their clients to take the "wait and see" approach because the lump was as small as a pea or just because they dog has had many similar lumps in the past, and they all turned out to be benign. It's easy to get a sense of false reassurance just because the dog has had many lumps in the past, and they all turned out benign.
There are countless stories, though, of dogs who end up with cancer just because of that "wait and see" approach. What happened? In many cases, the owner wasn't too diligent in keeping an eye on the lump until they noticed it's three time the original size, or the owner may have forgotten what it looked like in the initial visit six months prior (it helps to take routine pictures and measurements of the lump to keep track).
A needle aspirate is then done and pathology report reveals the big "C," and the vet calls the owner, who is in disbelief. The surgery now is much more invasive than it would have been if this were caught earlier, and the prognosis may be guarded. If the owner waited a bit longer, the cancer could have metastasized to internal organs, which could have been a death sentence. Not a nice ending to a story that could have had a totally different outcome!
The bottom line? Play it safe, and have your vet check the lump. Chances are high, most vets will recommend a fine needle aspiration. If your vet tells you to remove the lump surgically without doing a fine needle aspirate first, consider that the surgery can be a shot in the dark—meaning risky business.
Always have lumps removed once you know exactly what you are dealing with! "Why?" you may wonder, "Isn't it good to remove the lump once and for all?" The thing is, depending on what the lump is, the surgeon will need to take a conservative or a more aggressive approach. For instance, in the case of a mast- cell tumor, the skin will need to be excised with a very wide margin; whereas, with a benign growth that bothers your dog, a small cut may do. Veterinarian Karen Becker suggests always getting a confirming diagnosis so the surgery can be carried out accordingly based on the type of tumor.
A last piece of advice? If it turns out your dog has cancer and you can afford to treat it, your best bet is to have a specialist deal with the surgery. This way, your dog will be in the best hands possible, and you up the chances for clean margins and a potential one-time surgery.
