How does that explain Pugmire? What? Pugmire isn't popular? I withdraw my objections.In addition to the other reasons, it's probably because people want to have dogs, but they don't want to be dogs.
Other than Palladium Fantasy, who has a canine race that are part of a militant empire, most of the dog type characters I've seen are in science ficiton.
Rifts: Dogboys
Traveller: Vagr
Teenage Mutant Ninja Turtles & Other Strangeness: Mutant dogs.
Gamma World: Mutant dogs.
I am drawing a blank. I don't think I've ever saw a dog in TMNT or Gamma World and I've never played Traveller, but I've seen people play Dogboys in Rifts. Maybe you're right.
