Oooh, make your mom go look at the Lab puppies - they will melt her heart. Even if you don't end up with one of these particular pups, those Labbie eyes will make a dent that will bode well for future doggies! Make sure the pup would be able to live inside, explain crate training to your mom, and research research research! Just about any yard is "big enough" in my humble opinion if the dog gets enough exercise - walks and play time in and outside as well.
