Over the course of the 1st year, you can increase exercise with your Boxer, until he or she is meeting the requirements of an adult dog.
A Boxer should have a brisk ( 20 minutes for a puppy, 30 minutes to 45 minutes for an adult) walk each day, given that the temperatures and weather are not extreme. Do not bring your puppy out for walks until all puppy shots are given. If your Boxer enters an adolescent stage from around the 14 to 22 month mark where the Boxer seems too skinny
, keep up with exercise and a super-nutritious packed diet as his weight works to catch up to his height.
On very cold days, walks can be kept much shorter. On very hot days, head out in the early morning or later in the evening when it's cooling down. Having 2 walks a day is just fine for adults, especially if you must keep the 1st one of the day shorter than normal. If you keep your Boxer inside and the living quarters are rather small, exercising outside twice per day is best for this breed.
The Boxer dog should be given an opportunity to actually run around for exercise 2-3 times a week. This can be done in a large, fenced yard. If you do not have a yard, finding a large open field is great, as is a controlled environment at a dog park. Naturally athletic, this breed will love to run after a tennis ball and enjoy using all of their muscles.
You can be creative in the type of exercise that you provide to your Boxer dog. This dog can be taught to catch a Frisbee, always fun for both owner and dog. You can train him or her to run along side you as you bicycle, jog or inline skate. This breed, in general, loves to hike alongside their owner...
So any trails or such that you can handle, he or she can as well. Swimming can also be a great way to exercise muscles for both of you.
