Those that do canicross, what age do you start any serious running with your dogs? I would like to get back into running and used to go out regularly 3-4 times a week but my dogs just ran loose. I have recently bought a harness, line and belt and would like to have a try at Canicross. Sadly I do think I will have to wait a few more months before taking my youngster out as he is 8 months (GSD). I am guessing the minimum age for him would be 12 months but probably ideally nearer 18 months? Any tips or advice welcome.
