Honestly I never really thought about it? The dogs have been around all sorts of animals at my dad's farm, when we added chickens, it wasn't a big deal -- often when we throw out food scraps you will see the chickens jumping at the dogs to try and steal their food! And they are both cattle dogs, they just all live together in harmony! Could something happen? Well, I mean it could, but it's more likely a chicken will have something else happen to it before one of our dogs hurts them...and we definitely are low on what animals even come close to the house with the dogs running around peeing on everything all the time and trying to "chase" every turkey vulture in the sky
