Deciphering whether a Pokemon is based off a dog or not is fairly debatable, but here is the best list I can come up with:
I've boldened the ones who I think are the dog Pokemon of that generation (i.e. common and cute Pokemon that eventually turn into beasts) but I guess that's a matter of personal opinion.
Feel free to comment any other suggestions to this list.
Hope I helped. :)
