Owner guide - Train your puppy to a leash

Train your puppy to a leash as soon as possible. Mastiff’s can reach 200 pounds at adulthood and the last thing you want is to be pulled around by the grown dog.

DOG FAQ - Do Mastiffs Bite?

Any dog bites if hurt, frightened, or threatened, but a Mastiff that is properly trained and socialized will typically not bite except as a very last resort. Do NOT let a puppy (of any age) bite anyone or anything (except its litter mates) in play, since they NEED to know that biting is not allowed. They will still bite if there is an absolute necessity, but will not try it any other times.

DOG FAQ - What are Mastiffs like in the house?

Clean, quiet, and undemanding. Heaven to a Mastiff is a rug beside his owner's chair. Mastiffs are naturally clean (except for slobber), and quick to housebreak. Most adult Mastiffs don't chew what they shouldn't, and they don't get on the furniture (unless you let them).

If you do let your young Mastiff on the sofa, just remember that they grow FAST, and it is unfair and quite unreasonable to let the dog learn to enjoy something, and then decide the dog is too big to get up there any more. Mastiffs have long memories, and are much easier to train correctly the first time than to retrain to get rid of bad habits.
