But remember that a puppy is more work than a human baby. :lol: I would stick to the 4 rabbits, to be honest, but I am not a big dog person, anyway. If I was a rabbit or a cat or some other quiet pet, then I would not want a dog invading my space.
I was thinking of an older dog for that reason and they also get adopted the least.
Yes, I would always go for an older dog, after all the stories I have heard about puppies. I used to walk dogs for our shelter in Germany, and liked the older mongrels best.
You just never know what the bunnies are going to think of all this. Even if the dog is very friendly and doesn't want to eat them, the bunnies could still feel threatened and maybe attack it. My cat was very scared of my rabbit, because he would nip him if he got too close.
