Humans aren't the only ones to suffer anxiety. It's very common with dogs. My dogs are reactive towards other dogs, people, cars...anything that comes within a block of their yard. They would go bat shit crazy with barking out the window. I tired training, ignoring them, closing them off rooms with windows. Name it, I tried it. Nothing helped until I added a few drops of CBD Hemp Oil to their food and traded their treats for Hemp dog treats. No more stress barking. I have calm and happy Shelties again.
