What's this lump under my dog's back leg near his stomach area?

Hello. This is a small tumor, probably benign, but since it looks a bit irritated I would have your veterinarian take a look. It may just require a watch & wait to see if it continues to be irritated, or your veterinarian may suggest removal & histopathology to identify the tissue type & make sure there is not anything further to be concerned about.

Good Morning, Sorry to see Baby Boo is having problems. This growth looks like it could be a small growth or tumor, especially since it appears raised and ulcerated and is not going away. Normally, your local veterinarian will examine the lesion and perform tests to see if it is in fact cancer, then recommend removal and laboratory tests to confirm what type of growth. In some cases, your veterinarian will simple recommend removal or an excision biopsy to send off for a histopathology report. In all cases, the sooner the growth is examined and removed the better chance of complete removal and complete recovery without it coming back. From my initial view of the picture, it looks like you need to get an appointment and have it check soon, but looks like everything will go great based on the location and age of your dog. Best of luck, and thank you for the question. Steve Popish, DVM.

Thanks for using Petco Pet Education Center, formerly Petcoach! The pictures are a little blurry and it is hard to see exactly what may be going on with Marley's skin. A white bump on the skin can be a variety of things, including a cyst, blocked skin pore, wart, or another underlying issue. The bump on his stomach I can't distinguish in the picture. I do, however, recommend all abnormal growths be evaluated by a veterinarian to determine if they are benign (non-cancerous) or not. Typically a needle sample can determine this, and if any further treatment may be needed. Good luck!

Hello, this looks like a histiocytoma, a benign tumor. Fairly common in younger dogs, it usually spontaneously regresses without treatment. Have your veterinarian take a look to make sure that it is not anything else. Thank you for using Petco Pet Education Center, formerly Petcoach.

Hi there and thank you for using pet coach to address your concern. What i am seeing in the pictures is likely a sebaceous cyst that ruptured. These are common with older dogs and are benign. When these rupture there is a chance they will become infected so the best treatment is to have it removed to prevent this from happening. I would recommend consulting with your veterinarian about having this removed. I hope this helps! Please let me know if you have any other questions or concerns.

Thanks for using Petco Pet Education Center, formerly Petcoach! I'm sorry to hear Marvin has been going through so many issues. It does appear that he has developed a growth on his back leg, and I do recommend all abnormal growths be evaluated by a veterinarian to determine if they are benign (non-cancerous) or not. While it could be a cyst, insect bite, or wart, there are certain types of skin cancer (such as mast cell tumors) that can look similar to what you are seeing. I would recommend Marvin see his regular veterinarian and have a needle aspirate to help determine what the growth might be, and determine any further treatment that may be needed. Good luck!

Hello, & thank you for using Petco Pet Education Center, formerly Petcoach. The end of the nodule seems to have an ulcerated appearance which concerns me. Definitely have your vet take a look at this. I would recommend removal & having the tissue sent for pathology for identification. It looks like a full excision should be curative. Hope this helps. Take care.
