Let’s say we have a Biewer and a Yorkie that both weigh 3.5 pounds. Someone told me the Biewer will be bigger even though it weighs the same because its body has a different structure of length and wideness.
I don’t understand this because from what I’ve learned, they’re both Yorkies.
Is it true that the same weight Biewer will be bigger in size than the Yorkie? I ask this because my deceased 3.5 pound yorkie slept beside my head, and I’m considering getting a Biewer of the same size and want it to sleep in the same location. I was also told that Biewers tend to weigh more than Yorkies overall. Is that true?
There is no difference at all, other than color.
It is very possible that the person who told you this happened to see a big boned Biewer, perhaps next to a small boned Yorkie. And of course, each dog is an individual; a Biewer can be bigger than a Yorkie, and vice-versa.
Please keep in mind that no breeder can guarantee adult size. So, it would be hard to have two dogs (Yorkie and Biewer) that weighed exactly the same.
But, if hypothetically, you had two 3.5 lb. dogs, they would be extremely similar in body structure, as long as both were quality dogs that fit the AKC breed standard.
