The "leave it" command is one of the most important things to teach your pup! This is one of the first commands I like to teach to my students as it's easy to learn and can be used every day. It can also save your dog's life in an emergency situation!
Imagine the horror of dropping a pill or dangerous food item right in front of your dog. If your pup is like most, he will jump at the chance to check out what you dropped and may swallow it in an instant. Rather than spending thousands of dollars at the vet or crossing your fingers and hoping he'll be alright, teaching him to "leave it" will keep your dog out of harm's way.
