I adopted Maddie from a rescue on petfinder @ the sum of 125.00 without papers a STEAL imo.
she was 13 months old, spayed, utd on shots, and clean bill of health from the vet.
i couldnt even begin to get all those things done for her at that price, not to mention the cost of a yorkie alone.
sometimes people get yorks for free---and thats awesome. but seriously--what would it run you to take her to the vet to get shots and spayed? probably more than 200.00------if this is a true add and not a scam and you really want her--you should do it. but thats just me
