Graeme,
My sister used to exercise our Samoyeds by putting a harmess on them and they towed her around the area on roller blades..
They get up to some scary speeds and they love to run
Samoyeds are from the Spitz family of dogs are ares a close canine relly of Huskies and Malamutes.
I've had Huskies before and had them pulling scooter through the bush trails, and yes, they love to run. And they haul naturally, and love to do it, they follow trails naturally and they are easy to train to obey instructions. It's breed into them.
The 'experts' say not to have them hauling until they are 2yo, I'm not sure why - probably something to do with body development rather than brains or inclination. Bella is about 20mths so I'll start her as soon as I replace the scooter (stolen
).
