This is one breed where there are more potential homes than dogs. When we would get one in our shelter there would be an immediate waiting list. My sister has one and loves him dearly (along with her other 4 dogs and two cats.)
Because of the HUGE demand for this breed there are a LOT of back yard breeders - meaning a lot of health problems within the breed. Be careful where you get the dog. This is a breed that will be extremely difficult to find through a shelter or rescue group. If this is the breed you want there are plenty of reputable breeders, it's just a matter of finding one.
OK, before anyone gets upset - I am an extremely stong supporter of shelters, rescue, etc. All of our dogs are from a shelter, and all our cats are either shelter cats or rescued strays/feral. I'm also a member of Siberian Husky Rescue. I also know that certain breeds of dog are rarely seen in rescue. And, just like with cats, RESPONSIBLE breeding is important and appropriate.
