Can you imagine walking into a gym and seeing dogs lifting weights or cats jogging? We’re being a bit silly thinking of dogs and cats going to the gym, but we do have a reason. Just like human beings, pets that don’t get enough exercise can become overweight. Overweight pets can develop serious health problems just like we can. So, if you have a pet, part of being a good owner is making sure that your pet gets the right amount and kind of exercise.

Before you start your pet on an exercise program, be sure to schedule a check-up for your pet and ask your veterinarian how much and what type of exercise your pet needs.

Just like humans, pets need to be started out slowly. Over time, they will get fit and be able to exercise for longer periods of time. If you exercise alongside your pet, you’ll benefit, too!

Starting out, you might want to play with your pet for 15－20 minutes at a time. Gradually, you can turn those plays into several 30－minute walks or jogs each week. If your pet is especially active, you can extend them to an hour or longer.

Of course, some pets, such as cats, may not be easy to take for a walk or a run. These pets still need exercise, though. Don’t underestimate the value of energetic indoor play, such as games of chase, for these types of pets.

As you start exercising with your pet, here are some things to keep in mind:

★ Make sure your pet has plenty of water before, during, and after exercising.

★ If you have older pets, don’t push them as hard.

★ Watch the heat! If you are outside, exercising with your pet will be best early in the morning or later in the day.
