Thanks Al.
I had a Chow that killed my SIL's cats. One day my SIL called me and told me she was going to shoot my dog in the behind with her bb gun for killing her cats. I told her to go ahead, we had already tried everything else and she would not stop killing her cats. So when my dog went back over to her house she shot my dog in her behind. That stopped her from ever touching a cat or even looking at a cat again.
We did buy a bb gun for the rats that keep entering the pens and coop. I did try to use it to detour the dogs from messing with the chickens however it does not have enough power to go even 4'.
My dog that got into the chicken run and dispatched so many of my chickens went out to the road to greet my DH she thought and got hit and she is gone.
This is difficult as we adopted her as a 6 week old pup that was thrown out of a car while the driver was going down the highway.
Sorry to hear about your dog. We had one same situation thrown from car as a puppy. loved him to death for 15 years he died Mothers day this year.
The dogs we have now do not harm the chickens but I cannot seem to get them to stop chasing them. I guess since they run and scatter it is good training for the new neighbors murder dogs, but my dog only chases to scattter and the neighbors chases to kill.
