It is extremely unusual for a puppy to suffer from bloat. Eating and drinking too fast and then running around like mad is what puppies do, after all. Usually bloat does not happen until adulthood; one reason may be that the chest does not drop fully until then, which is supposed to be one of the reasons some breeds are prone to bloat (e.g., deep chested breeds).
So I would definitely treat this puppy with extreme caution through its life .. and I might also have a word with the vet, if that's possible. Bloat in puppies is so unusual I would just want to make sure it is real bloat.
