We have 3 dogs. Bandit (is mine, he's a 2 1/2 year old beagle mix), Lilly (my sisters havanese mix), and Juno (my sisters..... Mix..... I think he's part Pomeranian.).
The little dogs, had killed 3 rabbits that have gotten out, including my favorite rabbit, my [only] mini lop doe Olivia.
Lily is the alpha dog, hands down, and I think that Bandit might have chased the rabbits too, but mainly because they were doing it.
My sister has her dogs in a pen in the yard (because they kept finding ways to get out of the yard), but Bandit has the yard, and he can jump in and out of the pen. He loves the bunnies. My avatar is him with a little 2 week old REW doe from my first ever litter (mini rex). I also posted a picture of him with another baby, a broken blue otter Jr buck.
With the colony (which is still a work in progress), my mini lop mix does are escaping in a daily basis, but Bandit just ignores them. Sometimes if I'm having a hard time getting them back in the colony, I'll even ask bandit to help me round them up, which makes it that much easier.
He LOVES the babies, and they don't seem to mind him, either.
