Our foundation sire, Ch. Gropetti’s Lord Henry of MMRB is the epitome of what we are striving to produce at Mystery Mountain Mastiffs. “Hank” as he is known stands a spectacular 36″ at the shoulder and weighs in at 274 lbs. He has a tremendous head, massive bone and a top line second to none.

Hank is a easy going, happy and very intelligent dog who loves all people, children and animals. He’s OFA hips good, elbows normal, cardiac normal, patella normal, thyroid normal and cerf.

Hank was bred by Nancy Spiller at Spiller’s Mastiffs and purchased directly from Patti Gropetti as an eight week old puppy. I want to thank both Nancy and Patti allowing me to acquire such a wonderful dog and such a tremendous example of what a mastiff should be.

Hank has multiple group placements and has an international Best In Show to his credit. He has produced several champions to date, and has many major pointed offspring. Here are just a few of them.
