The North American Mastiff

---

The North American Mastiff is a newer breed created & curated in the United States. 20+ years ago, the founders of this breed started strategically picking dogs from different breeds & lineages around the world. Once known as “Deboar X”, the North American Mastiff began being popularized by Top of the Top Mastiffs & other North American Mastiff Kennels particularly on the West Coast in 2020. It still has tons of potential as there are several states in the US that do not have the breed in their area. They range in size, varying from 100-170 lbs healthy weight. Standing tall at 27-33 inches. Large heads ranging from 28-34 inches. Large bodies, muscular frames,
