Clicker training is a great way to train your dog (and cat) positively. No force or expensive equipment. I use clicker training on my year and half old foster, so it will work on any dog. You can buy a clicker at most pet stores for about $5. I bought a StarMark clicker which comes with basic instructions. First condition your dog to the clicker by clicking and then giving a treat. (My dogs are such food enthusiasts, I use kibble dog food for treats). When your dog performs a wanted behavior click and treat. You will be amazed at how quick your dog learns. Consistency is key. Karen Pryor is a behavioral biologist and a founder of clicker training. Always reward your pet for wanted behaviors when training, whether using food or “atta boy” and a pat on the head.
