I've noticed that she's been passing very hard, small stools, and straining when trying to have a BM. I recently switched from Acana to TOTW (more cost effective and she loves it, which is great since she's a picky eater)Not sure if that could have something to do with it. My other sibe is fine. Clover's appetite is good, and she doesn't seem to be in any distress. I tried some canned pumpkin(@1 tablespoon) and ground flax seeds(1 teaspoon) with no success. Also noticed she's not a big water drinker, maybe that is the problem? What can I give her to help move things along?
