These poor puppies are going to need a fourth round of vaccinations.

So you think I should ask for a 4th? I have no problem making sure Stella gets another, she's my baby and i'd do anything to keep her healthy. I was just trusting my vets input with this litter. I kept all of them til they had their 3rd round of vaccines.
