Teaching your dog acceptable behavior patterns and tricks is not difficult using techniques proven by dog training experts. Dogs are intelligent and loyal, but they need time to learn your "language" and the meaning of your words.
With patience and persistence, you can easily teach him the behavior you want and develop a close relationship with your dog. You can also use pooper scooper while training of your dogs. You can easily get the large dog pooper scooper online.
The most important aspect of dog training is consistency. In order to have a well-behaved dog, whoever looks after him or is usually in close proximity to him needs to know the correct commands. Always use the same word for the action you want.
If you teach him to lie down with the word "down," don't expect him to get off the couch with the command "down." Using commands to "hang up" one day and "wait" the next day will only add to the frustration and confusion on your dog's mind.
Dogs are intelligent enough to learn hundreds of commands, but one-word commands are easier to learn and understand than dogs. Same goes for executing sentences. A missed penalty is counterproductive to good behavior.
Let your dog know that you are happy with them by showing them happiness and love. Stroking and playing tells him that he is a good dog. When the sentence is passed, a harsh, harsh word will let him know that you are not satisfied with his actions.
