Hi, my grandpa has a female pit bull she is a senior already maybe 12 or 13 years of age. I noticed she has a bump on her butt it is pretty big I have noticed it increased in size over time because maybe a couple months ago it was small. What could it be ?

Unfortunately I can't see the lump on your dogs rear clearly in the picture. She may have a lipoma, which are common benign fatty tumors we see in older dogs, or something more worrisome. If it is on the anus, dogs can develop anal gland infections and abscess, as well as anal gland tumors. Any lump or bump that is changing and growing should be checked out by a veterinarian. A vet can do a fine needle aspirate of the lump to try to get some cells from it. Those cells can then be examined them under the microscope and hopefully give the vet and you a better idea as to what the lump is and if it needs to be moved or not.
