Some meat just doesn't agree with some dogs. I have one who is allergic to lamb and every single one of my dogs get loose stool after they eat caribou! They eat raw moose several times a week and never have that problem, only with 'bou!

The teeth sound normal for a puppy getting adult teeth in. Just like a teething human baby having something to chew on sometimes help--a kong, a frozen bone.

The refusal to eat is a very typical husky behavior. I have one who has eaten every third day since he was about 7 months old. He's perfectly healthy, just doesn't eat if he's not truly hungry. I'd weight 20 pounds less if I had that kind of discipline! If you see no other concerning symptoms, no change in behavior and the dog keeps drinking, do not be alarmed if your husky stops eating for a day or two occasionally. Do not offer him different food to entice him--you'll just end up with a spoiled, finicky husky! If he is otherwise healthy, he will eat again when he's hungry!

I just read in another post of yours that these are your first huskies. The learning curve is going to be steep, but fun! Enjoy the ride!
