We have an english mastiff. They barely shed, they are incredibly lazy, and very protective. They are large... Our's is still a puppy at almost 200 pounds (and only 28 months old!) but he is a great dog! We haven't had much trouble with chewing, he house trained very quickly, and is so concerned about pleasing us that we rarely have trouble with him acting up in the house. He does drool, though. A lot after he drinks. We keep a towel nearby to wipe his face after he visits the water bowl and after we dry him off, he's no worse than a normal dog. If you have any questions, don't hesitate to email me! ____@____.com
