Which are The Smallest and The Largest Dogs?
It is believed that the `chihuahua’ breed has the smallest dogs on earth. Even when full grown, it may weigh less than a pound. The Yorkshire terrier and the toy poodle are just as small. The smallest adult dog on record was a Yorkshire terrier that weighed just ten ounces!
St. Bernard is the largest dog. A full-grown St. Bernard may weigh more than 250 pounds. Thus the largest dogs on earth are almost 300 times as heavy as the smallest one.
