I'm by nature optimistic
but when it comes to bsl (breed spesific legislation) I'm not, therefore I won't predict a happy ending of this case.
Regarding American wolf dogs/ wolfmutts/ wolf hybrids they may range from high content bastards to dogs with a wolfy look alike. Our 2004 dog law forbid importing dog/wolf mixes regardless of content, which made problems to our racing dog comunity who are importing different types of racing dogs mixes from Canada and the US.
I guess it's commonly accepted that wolf mutts may be more unpredictable than pure bred dogs.
