7. Try Clickertraining
Get yourself a clicker, and use it when playing/working with your dog. Teach the dog to associate the sound of the clicker with a treat as reward every time the dog accomplishes any task.
With some training, you will be able to use the clicker without having to use treats as a reward every time but just with a lot of praise from you. You can find many guides on clicker-training like this guide I’ve previously written. Your dog will absolutely love the clicker as they will quickly learn that it’s a tool that results in a lot of rewards.
