Origins of Mastiff Breeds
Mastiff breeds are ancient dogs with origins dating to 3000 B.C. in the form of drawings in Egypt.

How Friendly Are Mastiff Breeds?
Mastiff breeds are gentle and intelligent. They are eager to please and form strong bonds with their family members.
- Guarding Instinct: Mastiff breeds have a natural guarding instinct, meaning they will not attack but will do whatever is necessary to defend.
- Training: Mastiff breeds can be sometimes stubborn. Consistent training commands from puppy years to adulthood are crucial. If you allow something when your Mastiff is a puppy, their great memory will tell them they can always do it—even when your Mastiff reaches almost 200 pounds! Set clear ground rules and stick to them.
- Aggression: A Mastiff may appear aggressive when protecting the home or family members but shouldn't be aggressive in nature. Thorough socialization is recommended, and intact males may fight for dominance.
- Family-Oriented: Mastiff breeds need to be close to family and should not be an outdoor-only dog. Isolation or long periods of separation can cause anxiety or destructive behaviors.
- House-Training: Mastiff breeds are easy to house-train and do not bark much unless they have a reason. They are also known to snore because of their long, soft palate, but this will vary with each individual dog.
