Coloxyl drops? Although I'm not sure if they help to make them poo, or only if they're constipated...I have a bottle here but can't be bothered to go and look at the directions
Does she get any extra water during the day? It doesn't sound like she's constipated as such, otherwise she'd be doing little hard balls...if there is nothing maybe she's just building up a big one for you?! Hope she's feeling better soon
