anyone keep bunnies?

I have a 6 yr old neutered dog that chases foxes down, like he does gophers,mice,and rats. He chases cats too, but leaves his 13 year old house-mate alone, who I claimed on the day I brought him home.
One time, he ran at 22/25 mph for 5 miles before I stopped him; and sprints to 30 on occasion. He's not very big (60pounds), so 30mph is a sight to behold! I'm pretty sure he would lie in the pen with those bunnies and never touch them, provided I claimed them first.
That might be just what you need.
Nice-looking coop
