Although I think the giardia has to continue to be treated, I would go with the vet's suggestion and do a bile acid test to look at liver function.
Breeders who test their breeding dogs for this usually give a one year health guarantee. A 24 hour guarantee is bare minimum, so I am guessing they did no testing...
