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.
Smaller breeds reach physical maturity earlier than larger breed dogs. Small-breed dogs that will grow to be 30 pounds or less when they are fully grown usually reach maturity around a year of age and should begin the transition to adult dog food at that point. Medium-sized dogs that will weigh between 30 and 50 pounds when fully grown will mature between 12 to 14 months.
