on average on his morning walk he will poo once or twice, and on his afternoon walk once, and it's obvious which one is a raw diet poo
Yes I've noticed that as well with my lot.
Lexi is on completely raw and I'm lucky if she poops once a day and then they are tiny.
We've just switched back to Arden Grange (as CSJ Lamb & Rice didn't seem to suit Ellie), and with that the other 3 seem to poop up to 4 times a day. Once first thing in the morning, once on their walk, once after tea, hardly ever on evening walk and then once before bedtime. Roly will definitely poop more than the girls.
