They are a very very good dog breed. And for those calling these dogs mutts, look at the lineage of your supposed Pure Bred dog sent from heaven above with no human crossbreeding, BIG NEWS, THEY WERE ALL MUTTS AT FIRST!! .(Self righteous morons).. Anyhow, We have an AKC english mastiff, AKC boston terrier, and recently aquired a 9 mo. old bugg as a rescue. Her temperment is amazing. she instantly loves anyone she meets, loves being on our laps, sleeping under the covers. She is for the most part lazy, but she has outbursts of play times, ten minutes at the most, then its back to the lap.Gets along just fine with the other dogs. Definitely has boston terrier traits, but also has others that I'm assuming are the pugs. Our boston has very few and predictable traits. So does the mastiff. With the bugg you get a little more IMO. In short, she is THE best dog i have ever owned, and i would not hesitate to get one. But if you are gone alot, its not fair to any dog, especially ones that are such human lovers. Get a cat for that.
