What's this growth on my dog's leg? Is it serious or will it go away?

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, 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! Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. Given the length it has been present, it likely represents something benign though you will not know until it is sampled. This is most of the time differentiated with a test called a fine needle aspirate which is easy, cheap and pain-free. Sometimes, a biopsy is required for a diagnosis. Have Latte evaluated by your veterinarian to have this test performed to try to sort out what the diagnosis is so that the best course of action can be determined. If it is a malignant tumor that warrants surgery, it is better to find out sooner rather than later. Keeping my fingers crossed that it is something benign!

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. There is no way of knowing for sure without an examination though this represents a reason to seek veterinary care. This is usually determined with an examination and a fine needle aspirate (FNA) or a biopsy. Treatment depends on the findings up to that point. I recommend you have Maddy evaluated by a veterinarian for further assessment and treatment. Good luck and have a good night!

This is likely to be a benign type of skin growth quite common in adult-old dogs. Unfortunately I cannot give you a definitive answer as usually there are two ways your vet can do that a part from examining it directly during physical examination. A biopsy can be taken under local or general anesthetic, otherwise a smaller sample through a fine needle can be aspirated (this technique is called FNA= fine needle aspiration). Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

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.

I would consider having this removed and biopsied. My concern is it is already ulcerated and will most likely need either oral or topical medication but if you wait to remove it and it continues to grow it is going to be very difficult to remove. The reason for this is because there is not a lot of skin in that location so they may not be able to close it adequately. I would recommend at the time of removal to biopsy it to determine the true cause of that. Thank you for using Petco Pet Education Center, formerly Petcoach.
