It's a bit concerning how some of these places seem quick to jump the gun lately and label these dogs as Biewers (or anything for that matter).
Fact of the matter is, you can't tell from looks alone if the dogs are Biewers, Partis, or Yorkie crossed with something else. I'm wondering if they are doing that to increase interest in the animals.
Poor little guy. He's a cutie for sure. I hope someone gives him a good home.
