French bulldogs are active, intelligent, muscled, and usually pretty small. Their personalities are affectionate and playful, and they make great family pets. They do require regular grooming, however; their coats should be rubbed down daily with a rough cloth, and you'll want to keep a constant check on the length of their nails and health of their teeth. One caveat: Because they have such a short nose, expect them to snore when sleeping; you'll have to keep a watchful eye on whether they are having difficulty breathing. If so, take them to a vet as soon as possible.
Chows originated in China and have long been appreciated for their beautiful frames and dignified manner. They don't do well with strangers, which is where they get their reputation for being aggressive, but they have a fierce loyalty to their owners and family. If you adopt a chow, be prepared to pay close attention to their grooming; a chow's thick coat requires lots of brushing --especially during shedding season. Chows aren't the most active dogs, but a daily walk can help keep them healthy.
