Good stuff that, i used it when i wanted to put a bit more back on one of my dogs, just added a little amount to the normal feed three times a week, a sack lasts a long time aswellyour right it lasts a long time. I've currently got mine on the bigger chunks but i prefer the small stuff. And I always soak it otherwise they seem to drink a pan or 2 of water easy. Plus I always find it easy, when at work all day if I forgot about taking the frozen meat out I can easy give it to them quick.
