10. Tibetan Mastiff
The Tibetan mastiff is one of the biggest dog breeds in the world, weighing 80 to 150 pounds. Buying one is no small feat since they go for $1,500 to $5,000.
These staunchly loyal dogs are double-coated in thick fur for the Tibetan climate, so they need to be groomed two to three times a week with a detangler comb.
Tibetan mastiffs yearn to be active, so you need a lot of space for them, which just gives them the opportunity to heavily shed all over the place.
