The only problem is you worrying about it.

Your dog knows how to eat raw meat with small and big bones. He was born knowing. He is perfectly built to eat and crunch and all is well with him.

And you ........ I'm more concerned about you getting sick over your constant worrying :-) Let this worry go and let your dog get on with his eating. He is more nervous when eating because of your constant fussing around him.

And consider how you would feel if I fed you all your food frozen because I was freaking out over you not knowing how to eat :-)

And I'm saying this with love and a little chuckle.

I know it's because you're concerned, but you can not fully love him and worry about him in the same space .. so how's about you give yourself and break and give him a break and just get on with the enjoyment of doing the man and his best friend bit.
