I don't know what kind of animals were around with Adam and Eve, but I think even if they had dogs, they could have been food too?? I don't remember any passage in the bible that said Adam killed, skinned and cooked Fido or Boots (a cat) and sat down to dinner with Eve, but then again, I shouldn't say anything about the bible - I didn't really ever read any of it.
I'm sure your basset hound is safe now!
