I just want to say, that "IF" you return this Pup to the Petstore, they will most likely put this dog to sleep or send it back to the puppymill it came from, whom will definitly put this dog to sleep.
While Giardia is a dangerous parasite, it can be cured
This pup needs to be on meds, it need nutrical, food and water and some pedialite.
I am crying thinking that they are on their way back to the Petstore, that poor pup is going to die without their care, the Petstore doesn't give a crap about the pup...
I don't understand why someone isn't trying to get this pup better and at the same time go after this store to pay the Vet bills - that is possible you know....
SO SAD...
