quick question on raw feeding pls

[cookham cocker]

Am experimenting with raw chicken wings with Ruby to help with anal gland issues. Just wanted to ask though if you feed a raw diet , without any bones , ie the natures menu does that still help with glands or do you NEED the bones?? Am assuming that just raw mince , egss etc will not bulk up poo enough.
Thanks again.

Bone content would be required, not only for the poo to be firm enough to help with glands, but also to get the right balance of nutrients... most of the pet minces contain ground bone...  Though the free-flow ones don't.
