my 16 month old toddler and our new 6 month old husky/lab mix

Question
my question is we just got this puppy about 2 weeks ago. she started out doing very well showing signs of some training but now shes steadily declining in her housetraining even though we keep her on a schedule. she also has a bad habbit of chewing on our toddlers toys and chewing on us and our toddler. on top of what training she does have wich we work with her on sitting and laying down and walking on a leash i take her for really long walks but those only seem to wear her out for about 2 hours then shes ready to go again. we also having a really hard time getting her to eat her dog food we have tried canned food with it and even chicken broth but she for the most part refuses to eat it. yet she will try and eat any table food and the cat food. but my main concern is that one shes scared of absolutely everything and two her constant nipping and three the fact that at most she only sleeps about two to three hours at a time and then decides its time to destroy things and chew on peoples toes waking everyone up.

Answer
she only sleeps about two to three hours at a time and then decides its time to destroy things and chew on peoples toes waking everyone up.

If this is the case, I would kennel train her. Keep her in a kennel at night. I am sure this is part of the reason her potty training is going down hill. I am sure she decides to pee somewhere at night if you don't wake up for her. Because she can to it at night, even though it isn't okay, she will do it during the morning.

Chewing.
She is a puppy, She is also a Lab mix which will make her really mouthy. I do not personally have a lot of experience with labs, but from what I do know is they LOVE to put things in their mouth, it is something that is bred into them being retrievers.  Do you have something that is appropriate for him to chew on? I would have a good stock of retriever rolls and a Kong or something that he can mouth on. Kennel training will also help with this behavior to, when she starts getting out of hand putting her in a crate with something to chew on that is appropriate for her will show her that she CAN chew on some things and when she is chewing on something she shouldn't like people, she gets put on a time out. Here is an article about it to explain it in depth.

She won't eat because she is trying to guilt you into giving her what she wants. When I have a dog that does this I make sure they DO NOT get what they want. I offer them their food every hour on the hour till they eat it. This is the Siberian Mind at work here. The thought goes like this.
Want cat food= can't have it= if I don't eat they feel sorry for me= they give me what I want.

 Siberians are very persistent. My friend's Siberian played this game for 2 months when he was just over a year old. He wanted the cat food. She had to keep the garage closed tight when he was out in the lawn, and when he was in opened it up for the outdoor cats. She also feed the indoor cat on a high counter so the dog couldn't reach it. Eventually he decided it was in his best interest to eat his food when she put a scoop of yogurt in it an mixed it with his food. When he went back to eating normally she then gave him what he wanted. Cat food is haigher in protein and fat then dog food, so this makes it tastier.

Here is an atical that covers all bases on the not eating issue.
