Hello and Welcome!!!
I am so happy for you that you have decided to get a Yorkie. You will discover that they are wonderful little dogs full of spunk and mischief and alot of love. There are a few things that you need to know about these great little dogs.
First of all they are more difficult to house train than other dogs. They have wee little bladders and they cant hold "it" as long. Also I swear that they are just plain stubborn LOL. It took me almost a year to train Chloe!
I recommend reading as much as you can about yorkies before bringing one home. They do have special needs as pups. For one I wouldn't bring a little one home before they are 12 weeks of age. A good breeder will insist upon this generally.
Make sure that you only deal with a reputable breeder. Mine required a lengthy interview before she would allow me to take home a pup and at a cost of 1200 dollars I was impressed that she wasnt simply trying to get me to take her LOL.
Yorkie puppies are prone to hypoglycemia which is when their blood sugar levels drop. Make sure that you are well informed regarding this issue as it can be fatal. It is easily treated with some Nutri-cal but you need to be able to recognize the signs. They do grow out of this as they mature.
As puppies and even as adults they are pretty delicate little ones, we have learned the yorkie shuffle
in other words how to not step on your furbaby.
I have a girl as that is my preference. I have found that girls tend to be a bit easier to train and yes they are fun to doll up
There are differences in types of hair. My little girl has very fine cottony hair-- a bugger to keep from matting and requires daily brushing. Also Yorkies are known for dental problems. Be prepared to have some baby teeth pulled as it is common for some to not fall out. You will also need to brush your little ones teeth as they are prone to tooth decay. Also a big no no is rawhide. I learned that one the hard way. It gets stuck in their teeth and could require professional cleaning to remove.
The average weight of a healthy yorkie is between 5 and 7 pounds. I would be wary of any breeder advertising "teacup" yorkies. A very small yorkie requires special care. Chloe is a healthy 5 1/2 pounds and she is just a little scrap of fur
The only way to gauge what they will look like is through the appearance of the parents and of course this is not a guarentee just a guide. My breeder does specialize in dark coat yorkies and Chloe does have a beautiful tan and silver coat.
These are just a few pointers. There are many things to learn about these amazing dogs and there is a wealth of information not only here but also on the web in general. Your breeder is a great resource as well.
Hope this helps
Tina
