You should divide the total recommended feeding amount by the number of times you feed your dog per day to get the actual portion size per feeding.

Remember to have clean, fresh water available for your dog at all times.

Rated 2 out of 5 by from First time user I bought this for my small dog hoping it would be good for her. It may have nutrition but she does not like it all. She will let it set for an hour or more before she even touches it and then just a little at a time. The only way she will eat it at one setting is if I some broth to it. I am very disappointed. I will be going back to her old dog food now.

Rated 5 out of 5 by from Love this dog food! I have a 15 year old cocker spaniel and 2 King cavaliers ages 7 and 9. I have been giving them this dog food, forever! Their teeth is super clean and they have been (knock on wood) super healthy. The vet said do not ever switch!

Rated 5 out of 5 by from Food is agreeing with my dog but poor bag design My dog is doing well on this food. Shiny coat, regular, well formed stools. The new bag does not fold down and stay closed like the old bag letting in more air and oxidation. Keeping food in it's original bag is supposed to be best for food quality. Please make a more suitable bag for this. A Velcro type closing at the top would be fabulous!

Rated 5 out of 5 by from Small Toy Breed vs. Mini Chunks Iams was recommended by the breeder of my Shih-Tzu. I fed her the puppy food until she was a year old. I purchased the Small Toy Breed adult food when she turned a year old. By mistake I picked up Mini Chunks. Both foods look the same. She likes them both equally well. Which food should she be eating? Can you explain the difference? Is it important to feed her the Small Toy breed variety rather than the other? I, along with others, dislike the new packaging. It is difficult to pour from the bag because of the thick plastic-like seam that separates the flow of the food. I find I need to shake the bag as I pour and it falls all over the floor.

Rated 4 out of 5 by from Awesome food hate the new bag My King Charles Cavalier is now 9years old and she eats this brand everyday. I have never had a problem and she is still spunky and has no digestive issues. The only problem is the new bags it never fails that I’m trying to get a new bag open as I’m running out the door. I literally loathe these bags they rip poorly don’t close properly and make a mess. I wish they would go back to the old bags.
