The vet will do a fecal test to check for the giardia. U can give her canned pumpkin to firm up her stool. Giardia is a nasty parasite that is hard to get rid of. If u have other dogs I would prob get them tested too if she tests positive. Try to clean her butt and feet with baby wipes each time after she goes #2, until u can see the vet. Hope your baby feels better
u can pm me with question as we battled the nasty giardia already
