Hi Sorry Rumble is feeling bad. When Fergus had his explosive poop episode. We did get him tested for giardia, worms ect... He ended up with just a tummy virus. Vet had us give him 8cc of immodium twice a day for 2 days. prescription of antibiotic Albon and Metronidazole. We live near a lake with lots of rabbits and ducks unfortunatly Fergus thinks their dropping are yummy . Also put him on a simple diet of beef and rice and 1 table spoon of lowfat plain yogurt until his was solid. He was all better in 4 days now his poop is nice and solid. Good Luck and hope Rumble feels better soon.
