On the off chance that the most expensive dog breeds cost of a canine depended on weight, pound for pound, the Tibetan Mastiff would be a leader without a doubt. For example, a Red Tibetan Mastiff named Big Splash is the most costly canine at any point sold. His new proprietor dished out a $1.5 million to bring back home a then 11-month-old, 180-pound pup. The Tibetan Mastiff's size could without a doubt be scary and startling, however they're really an extremely warm family canine variety, but a piece distant and regional with outsiders.
