Recently we received a request from a customer of ours asking to explain how to make his dog pull. Perhaps other people could jump in on this topic and share their methods. All I can say is MOTIVATION, motivation, motivation. Not all dogs are born to be natural pullers. You have to motivate the dog! Hook the dog to a bike, scooter or just to your waist and have a friend run in the front of you calling your dog. If the dog moves forward and pulls, praise the dog. Repeat, repeat, repeat. 😉
We offer a really nice book in our HDA store. The name is Skijor with Your Dog http://harn.es/SkjBook. This book gives really good instruction on how to teach a dog to pull. Also, this is a good sled dog forum to ask questions at: http://www.sleddogcentral.com/forum/
Stick to a defined trail, a wooded trail works well. Stop before the dog gets bored or tired. Join a local club!
