The recommended feeding amounts are per day and can be split between multiple meals a day.

The feeding instructions are a bit confusing to me. Is this supposed to be mixed with water?

Big dog loves the big bites!

Our (curvy) Weim loves the big bites of this food. He inhales regular kibble but it seems he takes more time to chew this food. He seems happy so we're happy.

I have a Great Dane and he was on Royal Canin 18-24mos large breed. It is now time the change being he turned 2yrs old. The Royal Canin Great Dane food the pieces were huge size of a chicken nugget. I then tried Royal Canin Giant adult and pieces are still way too big. This huge pieces would be good for a dog that eats to fast and you want to slow them down. No good for my dog.
