I bought my husky puppy yesterday, and it has not taken a bite on any food yet, doesn't at all. Bought the best dog food , today I tried giving it milk but it just vomited the milk out a few minutes later.the puppy is around 8 weeks old by the way. What may be the problem. I am very worried. I know the husky dogs tend to be very active, but this one is passive and sleeping all the time.
