We use food rewards to reinforce desired behaviours in your training. There are all kinds of treats available, from basic kibble to commercial treats to home made ones. High value treats are usually meat or protein based and can be cooked, cubed pieces of chicken or beef, bacon or cheese.
Dog blogger Eileen Anderson has two great tutorials on her blog about making really desirable treats for your dog. She recommends using food tubes filled with all kinds of doglicious concoctions in her post The Secret to Filling Food Tubes and she shares her terrific recipe for Non Crumbly Dog Treats.
