My new puppy is low energy, not eating, and feels hot. Is this normal?

I don't think it's necessarily something to be worried about at this stage. It is not uncommon for huskies and husky-type dogs to be picky/light eaters. She may be low energy because she is unsure of her surroundings. You have only had her one day. Don't force her or push her to be social if she doesn't want to be. If she is vomiting or having diarrhea she should see a veterinarian ASAP.

If she is of normal body weight I would not be concerned. Many dogs these days are overfed and too fat. I doubt she will be starve herself. In my entire veterinary career I think I have only told 1 or 2 people that their dogs were too skinny. It is very rare. I suggest you get a scale and weigh her once a week and keep a log. When Amelia goes to the vet next take the log with you and you can discuss it with them. Has she been dewormed? Is she up to date on her vaccinations? She is supposed to have a round of vaccines at 8 weeks of age, 12 weeks of age and 16 weeks of age. They should be dewormed at each of those vaccine appointments too. You really need to make a relationship with a local vet especially if you are a first time dog owner.

Hope this helps. Best wishes.
