Dog came over again this morning but my chickens were thankfully locked up. I am in the process of putting up a quick electric fence and trying to find ways to dissuade the dog from returning.
Right now the dog has had two exciting days of chasing around chickens, so he will keep returning.
Other than the electric fence, what non lethal deterrents can I legally try? bb gun? pepper spray? maybe some product I can put down? something smelly he will roll in and bring home? Looking for any ideas.
I have been dealing with this same issue - except, the dog has gone after me and killed several area cats. My non-lethal option is to shoot it with frozen paintballs because those hurt without penetrating the skin. If they explode, then the owner will see the paint and maybe, just maybe, he'll realize the next one might be a bullet. Anyway.....
What state are you in? Is your property legally posted against hunting, which includes hounds? If not, pop down to your town clerk's office and ask how to do that. In my state, we have to pay an annual fee of $5, fill out a form that's sent to the Fish & Wildlife Dept. It'll will provide a legal protection, if he says the dog is a on a hunt. My neighbor lied and said that and because my property wasn't posted at the time, the dog can go wherever it likes, basically. Posting the signs provides a bit of a legal protection and can prevent the owner from stepping on your property to retrieve the dog - should you catch it.
Because it is a hunting dog, you should call the police, the game wardens, and your town officials. Blow up their phones EVERYTIME the dog sets one paw on your property. Make sure to get a report from each of them. Eventually, this will start costing the owner money and should you have to use lethal methods in the future, you'll have the documentation to back up everything.
If you have to shoot the dog, call the police immediately afterward. Let them contact the owner and they'll be on hand to deal with him.
