This depends on it's backround, training, and environment. If you are raising this puppy with your aunts dog he will learn to get along with smaller dogs. This is all up to you, if you train your dog well, then the dog should be fine. It is somewhat in the nature of huskies to attack and kill small animals. I have know 3 huskies all raised by different owners, one of which was a professional dog trainer, and all three of the huskies have attacked, and one killed a smaller dog. These were all really good owners, they used positive trianing, but it was just in the dogs nature. You have to do a good job at raising this dog or you aren't going to be too happy. Also; Puppies are a lot of work I got my first puppy at 12 years old, and for the first two or three months, I was considering getting it to a new home because I wasn't used to doing that much work, finally I got into the pattern, and I loved my new dog! Dogs are not easy to take care of, and they cost a lot of money! So good luck!
