My little one lucky is about 12 weeks give out take a week. He’s been doing great no issues. Then in the last week started having loose stool. Occasional had a bad odor. But not bad. But yesterday it became watery but didn’t have a bad smell. Stopped his ebsilac formula and blocks and greens and started pedilyte. Up half the night to make sure he was hydrated. He woke up this morning doing ok. Started back with formula. Tonight again his stool is watery and his bottom is so sore he cries when he goes. Started back on the pedilyte. Stool smells bad again. Not like death but like c. Diff but he hasn’t had any antibiotics. His diet hasn’t changed. I keep his kennel clean. Onetime he goes I clean it as soon as I see it. He’s getting lethargic. Please he’ help. TIA
