Ive got a border collie so far hes fine with the chickens but he doesn't go in the run but other than curiosity if they making a noise he dont take any notice of them.
Here are some of mine missing in photo is a my old choclate lab, she is kinda blind but is still a varmit killing girl and great with all the animals that belong here.
We have five mini dachshunds. They are all great around the girls. However one of our dachshunds is a rebel and I'm always watching to make sure she doesn't do anything wrong. One of the hens we received was attacked by a dog so she now attacks back. It was so funny to see Piper (our rebel dog) chased by Dixie our chicken. Never saw her run so fast before. But Piper still likes to follow them around the yard. I tend to keep my eye on her because of that.
Golden retreiver. He's great at keeping other animals out of the yard, and only occasionally runs through a group of chickens to watch them scatter. He never hurts them though.
