Hello Everyone!

I had to look up Pomchis because I am not familiar with them. They are a cute little dog with a lot of personality.

It would matter what breed of rabbit you get. Rabbits litter train and they might follow a few rules, but mostly rabbits are independent.
I don't think your dog could hurt a rabbit. I would worry about a larger rabbit hurting the dog. Rabbits have a solid kick.
I would think a small to medium size breed of rabbit could work. I wouldn't leave them alone and unsupervised. 
Of course when I have had rabbits I don't leave them out of the cage unless I am home to watch them. Rabbits are great at chewing things so you have to rabbit proof anything electrical. The dog will be much better behaved.

It would matter how you introduce them. If they start off well  they could get along okay.

Let me know how it goes.
