Without seeing it in person it is hard to know for sure what the growth is. It is not likely a wart. Warts are caused by viruses and often seen in the mouth of dogs. This may very well be a benign skin tag/growth, but with any lump an evaluation by your veterinarian at your earliest convenience is recommended. They may take a small needle sample and look at the cells under the microscope to get more info and make sure it is nothing to worry about. They can also discuss options for removal if it is growing or if it is bothering pogi.

    Thanks for using Petco Pet Education Center, formerly Petcoach! These could be benign or malignant growths. 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 Cooper evaluated by a veterinarian for further assessment and treatment. Good luck and have a good night!
