Do you cut your dogs food up?

So, I've started feeding Molly ox heart, and have cut 1/4 of a heart into 3-4 reasonably big chunks.
The mother in law has then decided that it needs to be cut smaller........
Is it just me who thinks a wild dog wouldn't have someone there to cut their food up for them? Wouldn't they just rip chunks off of gnaw on it?

Never! But I don't feed raw so don't need to, I mix it though!

I have to, to an extent, because Dempsey is too thick not to try swallowing everything whole! But I only cut it to about 3" or 4 " strips, about 4" or 5" wide.
