Puppies need five minutes of exercise per month of age up to twice a day, according to the U.K. Kennel Club. In other words, a 3-month-old puppy will need 15 minutes of exercise while a 4-month-old will need 20 minutes. This may take the form of low-impact activities like swimming or playing with small dog exercise balls. You can also take your puppy out for short walks on a leash.
Though exercise needs are based on a dogâs age, breed, size and overall health, your dog should spend between 30 minutes to two hours on an activity every day. Breeds in the hunting, working, or herding groups (e.g., Labrador retrievers, hounds, collies and shepherds) will need the most exercise. If your dog is in one of these groups and is in good health, she should be getting at least 30 minutes of rigorous exercise along with her 1-2 hours of daily activity. Requirements aren't as easily established for every other dog.
