I love the "teapot yorkie". My Bruiser is 12 pounds at just about 5 years. He was 7.5 lbs for the longest time and then last winter he just got bigger. The vet says he is completely healthy and not overweight. He's perfect! Our whole family jokes and calls him our "porky yorkie"
There's just more to love. Big or small, they are adorable no matter what!
