How to keep stray dogs away from backyard
Don't leave your pets' food outside.
A sure way to attract stray dogs to your yard is to leave your own pets' food outside where strays can smell and get to it. Most strays will be hungry and looking for food.
If you feed your pets outside, make sure you bring leftover food into the house once your pets are finished. Keep trash tightly bagged and canned.
