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.
Medium-size dogs are at the midway point between tiny and massive canines, and both height and weight factor into the classification. Medium-size dogs generally weigh in the ballpark of 35 to 65 pounds, according to Kim Williamson of Animal Planet.. In terms of height, medium-size dogs are usually from 1 to 2 feet tall, measured from the ground to the withers or shoulder.
