My family is about to get a Whippet from a breeder in Atlanta and it will arrive on Tuesday. It's a runt, but that is better for my family because we have two cats and we do not want a massive dog around our house. Because it's a runt, would it train differently than any other dog? I have read up on house breaking on different websites but I would like some more information if someone would take the time to respond. Thanks P.S.- I think it was crate trained and it is a two year old male.
