According to Entirely Pets, good puppy training treats include Liver Bits Treats, Crazy Dog Train Me! Treats, Wild Alaskan Salmon Treats, Pet Botanics Healthy Omega Treats and Simply Wild Natural Dog Treats. All of these choices are nutritious and act as positive reinforcement during training.
Dog treats are a vital component in training puppies because puppies' have a strong sense of smell, and they can sense the treats from up to 20 yards away. Once a puppy smells a dog treat, the owner or trainer should wait until the puppy is calm and submissive. Puppies who are excited or over-stimulated should not be rewarded with treats, until they tone down the behavior.
