I have a Cavalier Spaniel/Cocker Spaniel mix and he's generally great with other "prey animals" (we have 2 rats and a rabbit, and the most he does is get low on the floor with his butt up in the air, ready to play), but would chickens trigger something in him that would make him snap at them? The only time he ever got aggressive with any of my animals was when my clueless kitten tried to steal his food, and my dog took a bit of fur off of the cat's ear. (The kitten still hasn't learned his lesson) A few summers ago, my neighbors let me bring one of their chickens over to my yard for a bit. The dog was fine, only he was persistent in sniffing the chicken. I guess the chicken got a little spooked, but my dog quickly stopped advancing when it was necessary. What do you think? Can dogs be compatible with chickens? Or would supervision be needed at all times?
