We have an intact 2 yr old male boxer. We are working with him!! [Warning: may be a trigger] He chased one a when they were about 3 months, she was fine just in shock. He got ahold of our speckled Sussex when she was around 4 months, she didn't make it. I've read a lot of dogs and chickens and i really want to believe he wasn't TRYING to kill her, she had no puncture wounds, she was soaked in slobber so I'm guessing he just shook her... A few days ago he chased one of our orpingtons, she only lost a few feathers, she's totally fine.
We've been using a shock collar to help with boundaries and it's worked most occasions. After this last one though we seriously contemplated giving him away..
he's a great dog, lets us know when anyone is even walking down the street. He's just a handful!!
Is training him hopeless since he's already gotten ahold of chickens?
