Kryptonite and four of his siblings came from a high kill shelter.  He is great with everything as you would expect in a young puppy.  We do expect him to be a big boy when he matures becuase he is already 12 pounds at only 7 weeks old.

 

These sweeties are ready to find a loving forever home after such a rough start.
