There's no one-size-fits-all answer to how often you should walk your dog, as it depends on a number of factors including your dog's age, breed, and energy level. However, most experts agree that all dogs should be walked at least once a day.

Some breeds of dogs are more active than others and may need more exercise. For example, herding breeds like Border Collies and Australian Cattle Dogs were bred to work all day long and as such, need lots of activity to stay happy and healthy. Other high-energy breeds include Jack Russell Terriers, Labrador Retrievers, and Golden Retrievers. If you have one of these breeds, you may need to walk them several times a day to tire them out.

On the other hand, some breeds are more low-key and don't require as much exercise. These include Basset Hounds, Bulldogs, and Shih Tzus. Once a day should be sufficient for these breeds.

Age is another factor to consider when deciding how often to walk your dog. Puppies and senior dogs generally have lower energy levels than adult dogs and may not need (or be able) to handle long walks. Instead, shorter walks more often may be better for them.

 Ultimately, it's up to you to know your dog and what they need in terms of exercise. If you're unsure, consult with your veterinarian for guidance on how often you should walk your dog.
