You'll be lucky if your dog doesn't join in on the fun. Some dogs are not cut out for repelling other dogs. Dalmations and Golden Retrievers for instance. I came home to find them just as merrily murdering birds as the neighbor's dog that broke into the pen. Like he was in the pen eating a bird, so I know he did it.I haven’t either. I have considered a dog for that purpose so that may the best idea.
