The top eight photos are current as of 27Jan2019 of Mattis. Mattis weighed in 200lbs at 13 months. His predicted/expected adult weight is 240-260. He is a big tall Mastiff with a beautiful head and honey apricot coat.

Top two pictures are of Mattis and Zelda. Mattis is getting so big, tall and filling out nicely. Mattis weighed 200 lbs at 12 months of age and he measured 33-34. Very impressive. Mattis has an impressive pedigree which speaks for itself. Both parents are  Champion Titled. Mattis looks very much like his Sire with the thickness of his Dam. Best of both worlds!
