The behaviour itself isn’t harmful although they may tell you something about how your dog is feeling. Your dog’s posture will tell you if they are having fun or stressed. In most cases, they will be joyfully happy – in which case they will be showing loose, wiggly, bouncing body language, maybe interspersed with playbows when they may hold their tail high before tucking it in for the next zoom, and with a relaxed even floppy tongue. This is completely normal behaviour common to all breeds and types of dogs – although it is most common in puppies and adolescents, and generally occurs less as they get mature. Even with joyful zoomies, the area in which they do it can be dangerous, particularly if they’re constantly skidding on laminate or hardwood floors or running into furniture. If you think your dog will harm themselves in the house, instead of trying to stop the behaviour, just direct the behaviour outside instead or if not possible, a carpeted area. You will be able to predict when the zoomies are likely to strike and make sure your dog is somewhere you can both enjoy them without any fear of injury.
