Mastiffs are housedogs. They can adapt to any environment, city or country, but they do best in a home with a fenced yard. Their exercise needs are moderate. An adult Mastiff will be satisfied with a couple of 20- to 30-minute walks daily.
Because of their great size, they’re not good jogging companions. They overheat easily, and their joints can be damaged from the stress of running. Walks are best scheduled for cool mornings and evenings. During the day, bring along water in case he gets hot.
Puppies are more active and need free play in a fenced yard, but until they reach physical maturity at 18 months of age, it’s important to limit jumping, long walks, and other exercise that could damage their still developing bones, muscles, and tendons. Let young puppies play, walk, or rest at their own pace.
Once they’re 18 months old, you can gradually increase the amount of exercise they receive to a moderate level. No matter what his age, learn to recognize your Mastiff’s signs of fatigue, because he’ll never let you know that he’s tired; he wants only to please you.
Mastiff puppies are nosy, curious, and into everything. Crate training is highly recommended. Not only will it keep them out of trouble and save your belongings from destruction, it’s an excellent aid to housetraining. This breed is easily housetrained, but a crate will help him learn to control his bladder and bowels.
Your adult Mastiff is just the right height to go counter-surfing, so keep food well out of reach. A swipe of his long, tapering tail can clear a coffee table. You might want to put breakables elsewhere.
Mastiffs of all ages are chewers and will chew on anything that smells good or looks interesting. Be diligent in letting your Mastiff know what’s okay to chew and what isn’t. He still might eat your recliner, but if you’ve provided him with plenty of chew toys and exercise, he’s somewhat less likely to do so.
Obedience training is a must for this giant breed. He may be sweet, but a full-size Mastiff who doesn’t have nice manners is unmanageable. The sensitive Mastiff is easy to train with positive reinforcement techniques such as praise and food rewards. Start with puppy kindergarten and go through basic obedience to ensure that you have a well-mannered, well-socialized dog who will react appropriately in any situation.
