Having struggled to find ethical wet food I have been feeding Dudley fish and chicken, although not at the same time. This is a topper on his Canagan kibble. Do I need to give him any supplements? If so what is the best? I cook both the fish and the chicken and freeze it in daily portions. The local butcher lets me have beef rib bones for him, he just eats what meat is on them and leaves the rest, these he has raw. He is a fussy eater but he vomited a lot when he was little. He has had the Canagan for over two years now and that seems to suit him.
