What are fatty tumors on my dog?
These fatty lumps, called lipomas, are very common, painless, and nearly always benign (that is, not cancerous and not life-or health-threatening). They are simply a clump of fat cells that have become concentrated in one location and formed a bump under the skin. They are most common in older dogs, though they can appear on young dogs or even puppies on occasion. There is no need to treat lipomas, though they can be surgically removed if they interfere with your dog’s ability to move, sit, or lie comfortable.
