Find a quiet place to train your dog. Get the best treats. Train your dog carefully.
You will want to find an area to work with your dog that is as free from distractions as possible.  By removing your dog from a noisy or busy location, you can help it to focus and learn how to high-five quickly. Never train your dog for more than fifteen minutes at a time.  This can cause your dog to become frustrated and hinder training efforts. When you train your dog, you will be rewarding them with treats until they learn how to high-five.  Make sure you find a good mix between healthy ingredients and your dog's favorite flavors when selecting a treat.  Store bought treats are considered safe to give to your dog.  However, you must still avoid over-feeding your dog. Apples (without seeds), strawberries, bananas, cooked sweet potatoes, carrots, lettuce and spinach are some examples of healthy and safe treats for your dog. When you reward your dog, you will have to do so at the exact moment they behave in a way you want them to.  Rewarding too far before or after they respond to your command will only confuse them and may accidentally reinforce poor behaviors.  At the same time, give your dog a treat and offer a positive response such as “Good boy”. Reward your dog just after they perform an action that you want to encourage.
