My Puppy, Teddy, was diagnosed with faint Giardia and treated with Panacur for 5 Days - which did make his already loose stools go to diarrhea. A few days after he finished The Panacur course his tools were pretty loose so he was put on 1/2 a 250 mg tablet of Metronodazole - twice daily - he has had 3 doses. Initially the stools started to firm up but then they went back to diarrhea last night - He now has reduced appetite - seemed hungry - eats a bit then hesitated then stopped after a 1/4 of a cup. I will be calling the vet but any advice/experience would be great.
