I am so sorry to hear that. I know how just plain awful that feels.
My husband and I got a poodle from a bad breeder over 4 years ago now and she died of parvo less than 2 weeks later. We were out the cost of the puppy plus the cost of vet bills. It is just awful.
Brittni is a healthy 1.5 year old Yorkie from Rock-N-Wood and we just love her. I'm so sorry to hear about your experience though, I know it is hard. You have my prayers.
