Hi guys
I am after some advice re feeding my new gsd pup, he is now 10 weeks old and has been home for 2 weeks, his breeder was feeding him a mixture of kibble and raw mince as she knew i wanted to change him to BARF as soon as he got home. The problem i am having with him is that he will not eat his chicken wings, he pulls of the meat and then plays with the bone, he has a little chew but he is not consuming the whole wing and i am worried that he is going to be lacking the nutrients he should be getting from the bone itself. He is currently having 4 feeds a day and he weighs 10kg, so i am giving him 10% of that over the 4 meals. His breakfast, lunch and tea is rmb's and then supper is turkey or lamb mince, i haven't introduced anything else yet as i don't want to upset his tum. He isn't too skinny although the vet did mention this morning when he was getting his jab that he was a bit on the ribby side. He has had a nibble on a lamb rib and again he pulls off the meat but leaves the bone

, how can i encourage him to eat the bone as well and should i be concerned about the lack of calcium etc.
Look forward to hearing your advice
