I would worry that Petsmart will try to sell you vaccines that your pup doesn't need, and I would not give her Lepto ever again, especially not in a combination vaccine. If it's absolutely necessary for her to have Lepto vaccine, it should be given separately, 4 weeks before or after any other vaccines.
As for now, she shouldn't get another vaccine for at least a month... it takes their bodies that long to process them and return to normal.
Glad your little one is doing better.
