I've a Beagle whose best bud was a Holland Lop rabbit (they even slept together in the same dog bed on the deck) and they remained such up until the Lop died of old age, had a Shepherd mix (I got her from animal shelter as a pup) that adopted three orphan opossums, and a pet raccoon (rescued as a baby after coon hounds killed the mother) that was raised around chickens and yet never bothered them (although I didn't leave them alone together unsupervised....why tempt fate). Some of the best friends in the world are the most unlikely duos. You know your animals better than anyone, and if you think they would get along, I say try it. And if turns out that they do, then wonderful! But just be prepared to accept it if it doesn't. Friendships like that have to come naturally to both. It cannot be forced, no matter how much we would wish otherwise, else the end results could be disastrous. I wish you the best of luck.
