Hello everyone. My name is Tina and I am new to the forum. I was recently given a male yorkie. I've owned poodles but never a yorkie. I've also always owned females but I am in love with this little guy. The biggest problem I have now is determining his age and what to call him.
I was asked to take him by a woman I know but am not close friends. She told me he was one year old and his name was Chewy. After she brought him to me, the last week of July, 2010 I asked his birthdate and was told May. I questioned the year and found out it was 2010. That made him 2 to 3 months old! After searching the internet for information I discovered he's not a puppy as he has the silver blue hair, brown and tan around the face and feet with white on his crown and down the front and his hair parts down the middle of his back. She says he is registered but she has not been able to get his papers from the breeder. I'm not too concerned about the registration since he was gifted to me except I'd like to know his birthdate. I had changed his name to Casper then last week she tells me his name is Shadow/Chewy. When called Shadow his ears perk up and he immediately responds but then he was responding to Casper as I'd had him a month by the time I found out his name. I checked his teeth and he has teeth all the way to the back, the front teeth are sharp. My husband thinks he is still a puppy due to the sharp teeth but I'm unsure about that. I'd read they usually reach adulthood around 6 months. He weighs about 5 pounds. This is very frustrating.

I've never owned a dog and not known their age. I've asked for the breeders name and phone number but have not gotten that from her. Would it be best to take him to a vet and have him estimate his age and how accurate can they get?
I will post a picture next time I visit, he's a cutie.
