My pit bull has a growing skin tag. What causes dog skin growths?
Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor guy!
Without seeing a picture it is hard to know if it is a skin tag or not. Since he is young it could be a histiocytoma, which are pink hairless button like growths on the skin. They are benign and tend to regress in 2-3 months. Skin tag are also benign. It is likely genetics and chronic trauma/pressure that cause them to form, as most skin tags are on the underside and legs where dogs lay on. They are normal in some dogs like boxers, pit bull and pit mixes, great danes.
If you want to post a picture I'd be happy to look at it.
Have a great day!
