I think there are many avenues to get to a well conditioned dog. If there was only one right way to do succeed then all of us would be on that page. It would not be smart to go a different route (wrong way) if there was only one way, if that makes sense.

I like explosive type work. I like to see the dog go from nothing to wide open in a blur. I like sprint work be it on a slat mill, a carpet mill or on a cable run. I am not measuring the recovery times like in the Lemm Keep. I have never based work times on heart rate but the principle of work-recover-work are similar.

I also like strength work. But like everything in the dogs, strength work has differing definitions for different people. I like to pull chains, usually about a 1/4 or so of the dog's weight. I like the dog to work under a load. I am doing strength work but not to the point of building big muscles, like pulling hundreds/thousands of pounds. I pull that chain at varying speeds for the muscular endurance, the dog is getting stronger but not all bulked up.

Interested in others opinions as well. EWO
