Mac's daddy says: We are originally from Boston, Massachusetts, and moved to Texas a few years ago. We wanted to get a dog and decided on a mastiff because my wife's brother had a French mastiff and he was a great dog. We ended up finding out about a mastiff that was going to have puppies so we said we were interested in a male. The puppies were born in late October two years ago. We knew he was going to be special because he was born on the same day the Red Sox came back to beat the Yankees in the 2004 playoffs. Mac weighs 200 pounds and is the sweetest dog we have ever seen. He truly is a gentle giant.
