Food training. Good food manners are important for any dog that will be sharing a home with people. There are two aspects to this training: making sure the dog is not food aggressive, and keeping the dog from begging for human food. The first part begins as soon as possible. Let the dog know that even if you take a treat away, you will be giving it back, and there is no reason to guard or defend food or treats. The second part requires vastly more patience but is rewarding in the end. Redirect the dog’s attention when human food is at hand, and do not reward begging behaviors.
