Knowledge: Dogs' diet is mostly made of meat, although they can also derive nutrients from grains commonly employed as animal feed like kibbles

Conversation:
My dog loves dog biscuits I think he is obsessed with them
Nice. They tend to be dry and hard, does it like it this way?
Oh no there are some that are soft and chewy, made my milk bone
Cool, do you buy the ones sold in a flat bone-shape?
No, but I have seen those. They even have some softy ones made from duck
I have never heard of those, but I have heard that manufacturers claim dry and hard biscuits help clean the dog's teeth.
Yeah there are some made specifically for that
Have you ever heard of ''Dog's bread''? it is made out of bran.
No but it sounds interesting. I heard it's bad to give kibbles to canines like dogs.

Response: No, it isn't. Dogs can derive nutrients from animal feed grains such as Kibbles.
