soo sorry to hear about barney's medical problems. you sound so loving & made the best decisions you could for your baby, after the fact it is so easy to say you should have done something. i just got back from the vet 48 hours ago & watched my little guy recover from all his shots it was very difficult, finally better today. i think due to the extreme small size of yorkies we all have to weigh our decisions more than we would with a bigger dog. my prayers are with barney & for you so you stop being so hard on yourself. bless you both
