I really do appreciate all of the comments and advice.
Bobby has had a 'recreational' beef rib which he managed to devour in two sittings - my OH just left him with it the second time! He's now been 'educated' in the need to remove the bone from him after 10 mins or so! Anyway, it didn't really constipate him much, just made him poop more. It's really hard because I am gaining all the knowledge here and then I go to work on a morning and hope that OH is putting it into practice and clearly this backfires occasionally. Bobby has been having some veg with his meals just to bulk them out a bit really. As Elaine said, the mince alone is a bit boring for him.
We have now switched Roxy (6) to raw too. She is less keen on it and takes a little longer to eat her meals. We will see how it goes with her but she needs to lose probably about a kilo and a half as, although she's a but bigger than Bobby, she is 16.4 kg and her ribs are harder to find. She is much less active than Bobby too.
We will get some chicken wings for Bobby, not sure Roxy will be interested as she wasn't really interested in the beef rib, and we will only give them twice a week as suggested. Where do you get the chicken feet from please Elaine?
We are learning but it seems to be going ok so far judging by output and energy levels
