Usually my advice is to let common sense rule. But to be specific, it's really a health question that you should consult with your veterinarian before beginning any extensive exercise program with your dog.

As a general rule, you need to build up your dog's endurance. I usually start a dog at a 10 to 15 minute jog, and over course of several weeks, gradually build up duration to anywhere from 20 to 40 minutes, depending on your dog.

By way... it's best to run your dog on dirt, gravel, sand or grass. Running your dog on concrete should be avoided if possible.

So, where am I going with this line of reasoning? Well, just remember that you should NEVER give a command that you cannot enforce, until your dog is 100%. And you'll know when he is 100% when his responses to commands are immediate! Even when you're asking him to respond around most tempting of distractions!

Do you want to be able to take your dog anywhere, and KNOW that he'll listen to you... even if tempted by another dog, a cat, or even a piece of food???
