I am very sorry for your loss of your first puppy. Now holly is so sick too. That is heart breaking. Have you got in contact with the breeder? Did you have any kind of health contract?
I got my Suzi and the breeder had already given her two rounds of vaccines. The breeder was even asking me about being around any other dogs because i had just cam back from a super pet adoption. I am in agreement that it does matter where you buy a puppy and who from.
Is your Holly a very tiny baby? A lot of little itty yorkie's can have a harder time with health problems. What did your first puppy die from? Was it from the same breeder?
I see that you live in CA. too. Can I ask what pet store you got your first puppy from? oops your in NC .
