Yes, a few of us on here run with our dobes. We are preparing Kobi as we speak for competing. His first race will be coming up soon, May I believe.
We run him in a specially made harness, this provides maximum comfort and pulling force for him....
The bungee line is then attached to a canicross belt, which goes around your waist and ensures that both running parties feel secure.
How old is Gennady? I wouldn't start running with him till at least 18 months.
Places to run, off road is always best, local woodland parks, or forestry trails are great to get started, lots of technical work for both owner and the dog, but soft enough underfoot. It is important to mix up terrain when training, harder ground can be equally as important as a softer ground, too much of one thing can cause issues either way. Try avoid too many miles on tarmac as it can be bad for both human and dogs joints not to mention pads, but avoiding tougher ground will keep dogs pads too soft and could lead to flat dogs pads too soft and could lead to flat footing. Mix up your trails for best all round training.
Lots of canicrossers use mushers terms to help drive their dog, you can use any term you wish, so long as your dog understands and you are consistent with what you say and how you say it.
“Go Gee”- Go Right
“Go Haw” – Go Left
“Forward” – Forward
“On by” – Ignore keep going
“Hike on” – Use more pulling power to carry forward
“lets go” – Speeding up or starting to go
“Steady” – Slow the pace
“stand/line out” – Stand still facing forward.
These are just examples of commands that I use. When training your dog commands, you want to repeat when they go in the directions and praise after the word, similar to how you would teach basic obedience, lots of praise when they are on right track will help them pick it up better.
Hope I've been of help to you
