We are trying to teach our 7 week old Victorian Bulldog boundaries, and it isn't going terribly well. He loves to go in the garden and eat the cedar mulch and as many times as we remove him and say no he goes immediately back to the area. I noticed some pet repellents at the pet store but I am wondering if they really work. I bought one called SHOO! and it did nothing. I sprayed it and the dog went right to were I just sprayed and started chewing. I live in Canada so some products I see online are not available here, but I guess I am wondering if it is even worth it to try another product. Thanks for any suggestions!
