My new puppy, Solomon, has been experiencing quite smelly gaseous episodes. He eats a grain-free dogfood - "Taste of the Wild", and gets raw grass-fed organic beef bones. I would have thought the grain-free diet would be less inclined to cause gas. He did have a slight bout with parvo a week and 1/2 ago. His test showed a "light" positive. He stayed the day @ the vet's and got IV fluids and antibiotic injections, as well as anti-vomiting/diarrhea injections and meds. The next day he was on the mend, eating and acting more puppy-like. Now he acts like a normal puppy (he's 13 weeks old). Any ideas?
