Hi,
You say your dog is quite young? Up to about 5-6months a puppy is understood by most other dogs. it is very rare for another older dog to be cruel. They may discipline your dog, but that is a bit of the idea. Donīt be too nervous, but ask the other owner first. But puppy with puppy is also crucial for learning to ajust leadership and play.
I think if your dog looks to the door and you think she is trying to get attention...then ignore it! There are worse things she could be doing. It is best that she can be incouraged to find a place while you eat and sleep a bit...
Donīt worry about the Husky side. They are also smart and very keen to learn and I personally think that the Labrador is a bit too friendly and willing ( possibly not so smart?) and the Husky is cooler and more wary. For me, it is great to have a dog that doesnīt want to sweet-talk every new person like a best friend, is smart enough to learn everything i have the time for and sensitive enough to pick up energy and feelings in the room. my Husky mix is beautifully aware of my childrens crys being from stress or pain, or normal play.
