Why Does My Dog Have a Bump on His Elbow?

Why Does My Dog Have a Bump on His Elbow?

Say you’re petting your dog and you notice a bump on the elbow that wasn’t there before and you’re wondering, “What is this thing and why is it here?” “Why does my dog have a bump on his elbow?” Well, there can be a lot of different reasons – here the 6 most common reasons.  

  1. One of the most common is a callus. A callus is an area of thickened, hardened skin that can form on the elbow if a dog is laying down on hard surfaces repeatedly.

  2. It could also be something called a hygroma, which forms when a dog lays down on hard surfaces repeatedly, and the trauma to the tissues on this bony prominence cause fluid to build up under the skin.
  3. It could also be due to joint effusion from an inflammatory condition inside the joint such as osteoarthritis. Osteoarthritis can actually make elbows swell up.
  4. In more rare instances, another cause for bumps on the elbows could be a tumor. It could be cancer or it could be a tumor that is non-cancerous. There’s lots of different tumors that are non-cancerous.
  5. It could also be an insect bite or sting causing a bump on the elbow.
  6. A bony malformation is another potential cause, maybe there’s something weird with the elbow bone and you’re feeling a bump there.
