It's important to start training your puppy while they're young, teaching them everything from how to sit and stay to how to ask to go out and relieve themselves. Dr. Richardson told POPSUGAR, "I encourage training through positive-reinforcement techniques that use verbal or treat-based praise." So make sure you have ample training treats on hand to show your dog what a good boy or girl he or she is when they do what you've told them to do.
