The size of the food is atrocious

The size of the nugget is SO big, she chokes. she is turning 2 so we are transitioning from JR to Adult. This is a 150 pound Great Dane and there is no way she

The size of the nugget is SO big, she chokes. she is turning 2 so we are transitioning from JR to Adult. This is a 150 pound Great Dane and there is no way she or even my 180 pound Dane could eat this. Unfortunately we had to throw the entire bag away and find a different food. The RC formula is fantastic but the nugget size is way off, even on the JR level. Disappointing and a waste of 100 dollars.

Pieces to big

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

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.

The largest pieces we can find in any food, larger than the Hill's Rx food.

This is the only food our pug (16#) will chew, she swallows any other food whole, so not good for her teet5h...

Super-fast delivery!

Not for the first time, living in a rural part of the USA, I’ve ordered from Chewy.com in the afternoon or evening, and the delivery arrives by noon the next day!
