Since Akira's training is going pretty decent, and everything I've read about huskies they are happiest when they have a task and plenty of excercise. I was thinking of training her on weights, or at least letting her excercise and run sometimes.

I am not really sure where to start. Is there a specific harness I must buy, or will the shoulder harness she has now work? Is there a specific age that she should be to start? Could being on weights affect her development?
Any training tips or advice are welcome. So far, most of the obstacles I have ran into, I have found a working solution here. Thank you.

The typical recommended age for any weight pulling is 18-24 months, when they have structurally stopped growing and the growth plates are set.

Once she is able to pull, a proper harness that is padded and distributes weight properly across the body is needed, so a regular walking harness will not do.

If you would like your dog to work for you prior to this time period, training is the best way to work her and provide her with mental stimulation and bonding to you.

If she doesn't come to you when called, gets up when in Down or Sit without release, is impulsive on walks or at home, or is hyper or nervous at home, then you have some goals that you can use to get her working for you.
