Rory loves horses! Mostly because of the yummy green goodies they produce. We couldn't keep him away from the piles when we visited my aunt and uncle's ranch in AZ for Christmas! But definitely no fear there.
He's great w/ my cats. Tries to play with them like he would another dog. One of them obliges, the others give him a nasty look and jump up high where he can't get to them.
I don't think I've ever had him around other animals. He seems very interested in birds, but always on leash, so I don't know what he'd do if he actually could chase one.
Dogs are not our whole life, but they make our lives whole.
