With your pup being 13 weeks, he most likely has had a recent vaccination which could skew any test result. Plus, he seems to be in a weakened condition now so drawing blood will only weaken him further, if only for a bit. No one here can tell you for sure what is best for your puppy, that should be between you and your vet. If it were my dog, I would hold off on drawing blood until he had gained some strength (is eating better) unless the vet gave me a compelling reason to do otherwise. I would concentrate on getting that baby to eat, keeping him warm and making sure he doesn't over-exert himself for now.

Praying all goes well with your little guy!
