Differences Between Wolves & Dogs?

Island situations are interesting. They would have started out with a small gene pool. That allowed them to develop one type of dog with little variation.
I had to look them up since I am unfamiliar with the breed.

They really are sweet looking dogs. They do have a problem with hip dysplasia, but that is to be expected in a small population. There is usually some inheritable problem.

I wonder how many other islands have developed their own particular dog populations.
