How to train a dog to come
Have the proper trainer mindset.
The dog will not learn if you do not have the right frame of understanding. A little research is in order before your first session, and it is always best to take an obedience class with your dog, and train as " homework ".
But for positive training, keep in mind : Your mood will be picked up by your dog. If you go into training in a funk, or feeling frustrated or angry, likely your pup will feel this too.
