Mastiff
A devoted mountain of a dog
Mastiffs 101
Working groupMake no mistake: The Mastiff is a very large dog; large enough to pull an adult human being off their feet or knock over children without meaning to. Fortunately, they are generally laid-back and relaxed around their people, as happy for a snuggle on the couch or bed as any other dog alive. If you have a Mastiff, be prepared for lots of comments about the size of your dog. In fact, be prepared for oversized everything!

Mastiff coat care and colors
Dealing with drool is the biggest grooming issue these dogs have, so you'll want to have towels handy wherever you go. Aside from that, the Mastiff's coat is relatively easy to care for, needing little more than brushing a couple of times a week and a bit more during shedding seasons.
