By MeLoveMyPet on in Medium Dog Breeds. There are big dogs and small dogs, and of course, there are the medium dogs. Dogs classified as medium are just about in the middle in terms of size and weight, defined to be between 13 to 24 inches, and around 20 to 60 pounds.
Briards are medium to large in size (bitches 22-25.5 inches, dogs 23-27 inches tall) and have a distinctive long coat that comes in tawny, grey, black, or a combination of those colors. They are a herding/guarding breed, as are German Shepherds, Rottweilers and Bouviers. I've never heard of that breed before.
