Hi, I have a golden retriever he is one year and seven months, I have been successfully able to train him for most of the commen orders however, my biggest problem is that when he is left off leash in the garden he targets for the roses and pulls them out from their roots then starts to chew on the stems. I have tried giving him a chewable bone instead but he hides the bone then heads for the roses or any other plant that he can pull out. When my boys run after him to try and put him on leash he thinks it's a game and starts doing it again. The end result is that he has to be constantly on leash when he is in the garden... Pls need any advice cause I hate having him on leash.........
