This is a really good way to build big muscle in dogs. Weight pulling is very good for all types of dogs including Pitbulls and all types of working type and mastiff dogs.
Using a Treadmill
This can be one of the harder things to teach a dog but once they get used to it they will love it! Its very good for making a pitbull super ripped!
Dog Weight Vest
Do not use a weight vest until a dog is done growing because you can cause permanent damage to their joints! Once a dog is matured this is a very good muscle building exercise!
Playing fun games like fetch
This is the most popular and most fun exercise! Play about 30-45 mins and your dog will get a good amount of exercise.
Using a Spring Pole
Make sure you install this on a steady surface because they will pull it down otherwise. This is a very good method for getting some energy out of your dog and will tire them out quick! Find a good pole and mount guide and then have fun!
