Why is my senior dog's penis dark and extended after chewing?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | neutered | 18 lbs

My chipoo is 11 and “fixed”, I found him chewing a blanket and his penis was out, longer than I ever seen in my life of male dogs and the color was not average, like black/dark red, should I be concerned or is this age related?

That sounds normal. He must have gotten excited when chewing the blanket. The color and size of each penis can be different so if he seems otherwise normal then it’s nothing to be overly concerned about. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Charlie.
