Martingale Collar

I'm using a martingale collar on my Malti-poo, does that hurt you?

We just spent allot of money to send to a cub camp three weeks. She has been back for 3 days and I'm trying very hard to put into practice all the things the trainer told me. But I feel like she constantly shakes neck when going for a walk, trying to stay on your line, is bad for your neck. Is it? The coach also told us that we should not let your dream us in our bed, you have to make her sleep in his box, so she knows she's the boss. But what is the point of having a cute fluffy puppy, if not embrace it, and those took things in a box

You should not be shaking her .... there is no need for that. Keep the leash short, their position in the heel and foot. Corrections strap should be in an upward motion quickly and without much force. Make sure the neck is well placed in the neck and / or leash corrections will take you anywhere. I at least put the box in the bedroom. For the dog, sleeping in your room is the equivalent of being able to access their "den", and can help strengthen the link between you and your dog. Why send her away? The training will not help unless you continue it at home, and how can you know that you are doing properly when these were not to see the coach's methods? I would call the coach and ask if he / she has a DVD version of a training session so you can be sure you are using the techniques correctly.
