It's quite possible that he's just hotter than your other dogs. I have a few who can't handle being inside for long periods of time without excessive panting. I have water bowls all over the house for them and tend to keep the house a little cooler than most people. Bring a sweater if you ever come visit!

If he's still in his winter coat, he's likely boiling inside. He'll start to shed soon and that may make him more comfy.

If he's acting normal in all respects, (as normal as a husky can act!) I wouldn't worry too much about it.

Congrats on the new addition!
