i would visit the vet, but we are short on money for a while, and it's too costly for just an brown townysis atm.
my dog has these black, flea-like things on him. i would just say they're fleas, but they do not jump, and frontline or anything we have used doesn't kill them. we bathe him once a week because his skin will dry out of we do it more frequently. they don't bite humans, and i don't think i've seen them on my cats. you can see pink on his tail because he bites it and stuff, so we put one of those cones on him for the time being. i've seen them near his genital area, and the tail, and where the tail connects to the body. i only post this in desperation because i don't have many options right now.
