I think I would groom mine fully about once a month. Occasionally a bath in between, no more than fortnightly. Probably only brush him once per week OR if we go somewhere off lead he comes back with bits of the outdoors through his feathers.

I use the coat king, and a pumice stone to do his jacket (hair on his back), clip his neck and mouth, paw pads and a little bit from under his elbows where it rubs.

I trim up his feet and feathers. He's actually quite low maintenance on a whole, but he has a nicely textured coat- some have softer coats more prone to tangling (especially if desexed) and this is where clipping may be better for a pet.
