I agree with Glacier, huskies do not play like typical dogs. They are rough and they usually are very noisy (lots of growling) when playing. When my siberian husky was a young pup there were a few times when I thought he was being truely aggressive. It turns out he was just a little brat. It takes time, patience, and training to turn them into the wonderful dogs they have the potential to be. I can't say for sure but I don't think getting a male lab instead would be a magical cure or anything...could you take the husky to where you got the lab puppy and see how she interacts with the other pups both male and female? I highly recommend spaying/neutering both dogs while they are young, 4-6 months.

You definitely have your hands full with two puppies. Did you research siberian huskies or labs before getting them? Huskies are not your average dogs at all, they can be stubborn and hard to train, they are prone to running off (can't be off leash), have a high prey drive (generally not good with small animals), etc. I don't have any experience with labs but from what I've heard they are mellower and easier to train than huskies. Either way you are going to have two very high energy dogs on your hands, I hope you have a fenced yard and plenty of time to exercise them!
