Alright, for the most part, socio-economic, all that stuff, is about the same.
A few things: Dogs, by their nature, are far less likely to go the SERIOUS type of Wild. Wolves, foxes, most four legged non-feline mammalian predators that are vaguely canine in appearance are reasonable enough for being considered " Dog"-types. There ARE dog-boys, no hermaphrodites- Or at least, they're more a specialty object.
One of the noticeable things is that the domestic breeds will have pretty strong differences. A chihuahua might be a very small, 4-4'6" foot girl, rather nervous around everyone, Great Dane a big melancholy but soft-tempered amazon of a girl, that sort of thing. Remember to check Wikipedia, lotsa interesting stuff to think about there.
There would be a definite submissive streak towards the person they " Bond" to. They can bond until they reach about the age of eighteen, and become very loyal to the person- This requires a certain level of care with the store clerks not to be TOO friendly with them, lest they find themselves making an unexpected purpose. Doggies are definitely more multipurpose, and they may be a bit overprotective, but they're generally willing to listen to their Master/Mistress.
There would be a fairly wide choice of sizes, and there would be, by nature, a lot of breed variations of dog girls. If you know a kind of dog breed that you like, just take personality traits from them- But of course, if you like a different kind of shape or size, there's no need for a dog type personality to be all-encompassing...
But yeah, looks like we're getting some responses, perhaps Elvi can create a game for us? I'm thinking, for the hell of it, Inugami: A Game For Bitches. >_> Yes, I AM a weirdo! But, BATL Exotic.
