You double their 3 month weight, not 4 month. I'm guessing you're going to have about an 8 pounder.
My chachi has a long muzzle and he is 100% pure yorkie.
Why do people feel it is necessary to put down someone elses dog.
If I saw one that didn't look like a yorkie, I might think to myself, but unless they asked for my opinion, I would keep it to myself. Does it make them feel good to make someone else feel bad.
I might have told them, "well he looked like a yorkie until I brought him here to be groomed".
