If you have a dog, chances are you've heard this question. And chances are you've probably given yourself the same answer: "As much as they can get!"

But the real answer is not so simple. The amount of exercise your dog needs depends on their age, their size, and their breed. It also depends on how much time you're able to spend with them during the day—and whether or not they live in a home with other dogs.

It's important to remember that just like people, dogs need regular exercise—but not too much. If your dog doesn't get enough exercise, they may become overweight or even develop behavioral problems like separation anxiety or aggression toward other animals (or people). On the other hand, if your dog gets too much exercise before they're fully grown and their bones have finished growing, it can lead to hip dysplasia (a condition where the hip joint becomes malformed due to overuse).

So what does all this mean for you? Well first off: keep track of how many calories your dog eats each day so that you can estimate how many calories they're burning off based on their activity level. Just like their human counterparts, canines' targeted time of exercise varies depending on several factors such as calorie intake, size/height/weight, etc. - just to name a few!
