Toilet training bells are one of the most effective and easy methods to teach your dog to let you know they need to go out (or anything else for that matter – for reluctant eaters, we sometimes give them ability to tell us when they are hungry rather than us deciding meal times for them)
Simply hang the bells on the door which your dog uses to go outside and train them to tap the bells when they need to go out.
Great for taking when you go on holiday or to visit other houses so your dog has consistency and can ask there too!
