These guideline amounts are a starting point and your dog may need more food depending upon age, activity, and temperament. In order to reach optimal body condition, you may need to adjust food intake. This represents the total recommended volume of food per day. 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.

Rated 5 out of 5 by from IAMS & CATS 15+ YRS Our family has used Iams dog and cat foods for over 15yrs. Many yrs ago one of our vets recommended Iams saying it was high in protein as well as containing other better, healthier ingredients and had fewer fillers. He also commented that because of better ingredients, the dog and cat's fecal waste was in smaller amounts and the waste didn't smell as foul. We noticed these two bonuses immediately! Our pet's fur ALSO became VERY soft and shiny. The two cats I've had over the last 15 years have been SO soft to the touch like silk. I would positively recommend Iams dog and cat foods. I've only used the dry foods so I cannot vouch for the wet foods. You will not be disappointed in Iams pet foods.

Rated 5 out of 5 by from The best!! My German Shepherd turned up his nose at Diamond Large Breed, Nutro, Fromm, and ProPlan across a span of two years. He LOVES this food! I'm so happy to get the extra nutrients specific to large breeds and relieved not to have to add or top the food with some kind of enticement. I have had to throw away so much dog food, because I didn't find it true at all that "if he's hungry enough, he will eat it". Maybe not every dog will like this, but my very picky and spoiled dog loves it!!

Rated 5 out of 5 by from Best dog food for my German Shepherd I started buying her the large breed puppy food and she loved it! She did very well on it and grew to be a big dog! When she was two years old, I gradually switched her to the adult large breed formula. She is thriving and very energetic! She is an indoor dog, but obviously gets her outdoor fetch exercise! I highly recommend this dog food and so does Jet!!

Rated 5 out of 5 by from Proven Quality over years of use I have raised several dogs using Iams and have had healthy long lives. I have had people suggest I not use this product but then they go on and tell me about all of their vet bills. My current Lab I rescued from a family that couldn't handle her. They gave me a supply of their cheap food which I used to gradually change her to Iams. She changed physically and mentally to a much happier dog.

Rated 5 out of 5 by from IAMS was recommended by my Vet. This was recommended by my Vet many years ago for my ferrets as it is high in protein. Our dog loves it too! Good for animals.
