I have waited 7 years for our garden and we finally have it – or at least the blank canvas. However, we didn’t have to wait so long for a stray dog to wander in and my kids to fall in love with it.The dog is in situ and this is my first year to see a little progress from newly laid shrubs and trees. NOW THE DOG IS CHEWING AND EATING THEM. Is there a spray or anything to use as a deterent ? Please help
