We kept our Clumber Spaniel puppy on this following collection from her breeder. At times we've introduced small amounts of other free taster packs of other foods. With the Kronch, she has very healthy looking stools and regular bowel movements. I can't say that for the other tasters. There doesn't seem a lot of waste. Her coat is soft and healthy. She is full of energy with bags of character. She isn't a big foodie, but seems to enjoy her meals and I'm impressed with the quality of the food at Kronch. Who wouldn't want a complete feed and salmon every day?!
