whenever people talk bout the spitz breeds they always seem to bring up the independant streak. and yes they do have it. they arnt the please cuddle me type of dog, but if properly trained from the minute they come into your house they are great. just like any other dog, most times its how your raise them, not their breed.
a husky would be more likely to chase things, but rarely chase to kill, its a game not a hunt. the idea that you can never let a husky off lead is silly. sure they tend to run alot but thats were training comes in!! not letting a husky run is like not ever playing a game of fetch with a retriever.
though i do not know much on collies i no that they are more of a dependant breed, meaning they have been working closely with humans for years, thats what they were bred for. im sure a collie would make a great family pet, but so would a husky.
i think you should sit down with your husband and go through the reasons why each of you want your breed and not the others, and remember any dog, if raised well, will fit into a family
good luck .. sorry for the long post
