The first step to a well-behaved dog during the holidays is to Introduce your dog to basic obedience commands such as "sit," "stay," “quiet,” and "leave it" to establish control and prevent unwanted behaviors like jumping or excessive barking. Another helpful idea is, if your dog has not yet learned to greet guests calmly place your dog in a safe designated space, such as your dog’s crate or backyard so guests can enter without being accosted. After the initial entrance, you will be able to focus on handling your dog for the greeting and in a better position to introduce your dog to your guests.
