My gosh, I just re-read your first post. I am blown away that a Vet would DOUBLE up on shots for a 4 month old tiny pup
This is INSANE!!! Do you know that the vaccine dose is the same regardless of size. They give the same dose to a huge dog as they do to a 1 lb. pup - and he DOUBLED it
If I were you I would be beyond livid AND I would be finding a NEW VET
