I have a 7 month old buff orpington hen that I can only assume is coming into her own as I caught my dog unusually "interested" in her and watched him attempt to mount her much to my surprise. I brought him inside right away of course but I can't believe what I saw! The terrible thing is they both have free range in the yard so someone is going to have to suffer and be enclosed. Has anyone else delt with something like this? Any tips on discouraging my dog? He has been fixed since he was a pup and is now 5 years old. I'm scared he's going to kill her with his "loving" if I'm not there all the time.
