A guy is drawn with canine traits like dog ears, a tail, and sometimes paws or a muzzle, usually leaning hard into a cute-but-filthy “pet” vibe. Scenes often play up collars, leashes, belly rubs, and submissive behavior while another man handles him, fucks him, or makes him beg like a needy puppy. Depending on the artist, he can look mostly human with accessories or more fully anthro with a dog cock and knot.
