Compared to Bostons, H1 Hybrid Buggs tend to be more clingy/ snugly, less ball crazy, less flatulent. Same energy level, intelligence. Barks more than a boston, easier to train, more keen on tug war and being chased. The most common colors are black or brindle with white on chest, curly tail. I've had 2 Bostons and 4 Pugs.
