Doesn't sound like you did your homework right. 500 for a yorkie is cheap and what you will probably get is a cheap dog. I paid 500 for a 1.5 year old yorkie girl who was registered too. APRI which is a load of crock. I was like you naive. What I got for 500 bucks was an absolutely LOVING, gentle gorgeous (in my eyes) yorkie with a WHOLE load of health problems. I thought I did my homework and studying too
If your looking for a pet companion, go for it. CKC papers, I wouldn't be getting so excited over them because I wouldn't buy a breeding dog that wasn't AKC or Canadian Kennel Club. Those dogs are going to cost you way more and are worth every penny. Please be careful and don't throw all the advice in the garbage, alot of people know what their talking about and some have years of experience to share with you, no need to be snotty or smart. I am not trying to be rude either but some of your replies come off a bit snotty to me. Again this is the internet so what do I know.
Goodluck the pup in the pics is cute, not sure if its all the same dog though, quality of photos isn't good. Oh and I'd be moving outta where ever you are and definitely not attending any of their fun dog things they do.
