Tux is a triangle shaped dog biscuit, many other sorts you can get but, a good old standard.I have never struck a resturant here that gives a doggie bag for uneaten food, it just goes back to the kitchen and out with the rubbish, thanks for looking in.

I agree with Golda on both thoughts. Very cute.

That's a new type of dogfood to me, we do get Purina brand here, but haven't seen Tux before.
