One of the first commands that you should teach to your Beagle is "fetch". Due to the instinct of this breed to hunt, if you, as the puppy's owner, teach this command which your pup has such an inner desire to know, your puppy will be much more open to learning other commands also!
Let's discuss the importance of one of the first commands that you will teach your puppy: To Fetch
1) Put a rather long leash on your dog and bring him or her outside.
Bring with you an object that your Beagle loves the most. This can be his favorite toy, etc.
Take the object and toss it a small distance from your dog.
Give the command, "Fetch," and allow your Beagle run after the toy - encourage this with happy, excited words.
