I know it is not yorkies, but this girl lets her min pin puppies go at 5-6 weeks old
I e-mailed her and gave her the reason why you should never let puppies go before 6 weeks old and it was best to wait until atleast 8-10 weeks but she never responded and her ad is still there
I reported her ad as offensive, because to me it is!!!
