The past couple days when Bruin & Lilly poop, the poop just crumbles on impact with the ground. Like the outside is "moist" but the inside is so dry, as if it was sitting outside in the cold temp overnight. Has anyone experienced this? I put it in the yahoo search engine and it came up with someone saying that sounds like poop from a dog with a raw diet. Which they don't eat raw. They eat NVI LID Lamb
