The puppy is a Yorkie. Im not sure if she means he only has 1 or only 1 has descended. I was told "he only has 1 testicle,Im just putting it out there"which made me feel uneasy like it was a throw away line. like saying oh the brand new mercedes you're buying only has 3 wheels. I have had pedigree dogs before and never had any trouble with the sellers but after our phone call tonight Ive just been left with an uneasy feeling.
