Giving your Husky a long line to run around and exercise is fantastic and
Training especially for recall on a long leash is great however . . . .
There are two main problems with using a long leash .
1. they can and do get wrapped around things, park benches, poles, trees etc.
2. If you are using even say a 30 meter leash if your dog is 30 meters behind you and starts running fast
it runs past you going faster. The dog can be doing in excess of 30 miles per hour by the time it reaches the end of the leash.
Can you hold onto your end when the dog is travelling that fast ?
what damage may be done to you and the dogs neck if it is attached to a collar and not a harness.
