SMALLESTLARGEST/ SHORTESTTALLEST BREEDS IN THE WORLD
We have listed below all the main breeds of dogs and categorized them in height order. The Small dogs at the beginning and ending with the Large dogs. If you can't put a name to a dog but know the rough size then this list will be of help! Please note that sizes are to the shoulder, not to the head. This is a better measurement of dog size than using the height to the head which would make the Great Dane the tallest dog, although it is not nearly as big as the Irish Wolfhound!
