Hi, my Beau was 15.25" and 20 lbs. at 18 weeks. He is now about 19.5" and 40-42 lbs, he varies a bit--trying to keep him leaner. He is pure muscle and large boned. His mother and father were both champions (his mother was at Westminster even). I know this breeder, and I think most sheltie breeders, litters varied in size.


I have always preferred the oversized ones - more to love! Our biggest girl was Asta at 18 inches and about 30 pounds. I called her my plus-size girl. Getting Ally, her aunt, who was 14.5 inches and 17 pounds was a real shock! She packed a lot of personality into that little body though. Her nick name (among many) was Pipsqueak.
