Barking, growling and howling are vocalizations that can all be stopped with verbal commands.  All three vocalizations are not allowed inside the dog park. Of course, there will be times when your dog will bark, growl and maybe even howl while visiting the dog park. These behaviors are natural after all. However, while in the park, even when no danger seems to be present, it is best to curb this behavior sternly and consistently. By discouraging it when it does occur, we are able to modify the dog’s behavior in that moment, preventing other dogs from joining in and keeping the situation from escalating.
