The first step is to choose the command you want to use. "Come" is a common choice, but you can use whatever command you like.
Dogs learn best when they're having fun. Start by playing a game of fetch or tug-of-war with your dog.
A marker word is a word or phrase that you use to mark the exact moment your dog does something you want them to do.
When you're first starting out, don't call your dog from very far away. Start by calling them from a few feet away and gradually increase the distance.
It's important to be consistent with your training. Always use the same command and always use the same marker word.
When your dog comes when you call them, be sure to reward them with a treat or praise.
If your dog doesn't come when you call them, don't punish them. Just start over and try again.
