Hi sascha k,

The difference between what veterinarians recommend and food ratings sites such as this one occurs because different criteria are valued. Ratings sites usually focus on the ingredient panel and use that to rate the diet. Veterinary nutritionists and PhD nutritionists overwhelmingly report that you can not tell anything about he quality of the diet by looking at an ingredient list.

The following quotes are from Dr. Remillard a board certified veterinary nutritionist taken from her site petdiets dot com

“Sorry. The ingredients list cannot and should not be used to assess the quality of a dog food. Please disregard the self proclaiming pundits who say you can. It simply cannot be done. In fact AAFCO and FDA guard against it.”

and “I recommend pet food brands that have high quality control procedures and monitoring in place. A review of the ingredient list on a pet food product is not a good way to evaluate or rank a pet food regardless of how hard or detailed some people have tried to be. The pet food bag information lacks the necessary information needed to fully and accurately evaluate pet food quality.”

Veterinary nutritionists ask questions like “Does the company employ a veterinary or PhD nutritionist? Who formulated the diet? Is a nutrient analysis available? What is the digestibility of the diet? What quality control is being used? Can the company answer basic nutritional questions correctly? Does the company invest in nutritional research? Is the marketing material appropriate? …..

You can find information on how nutritionists would recommend you to evaluate diet at wsava dot org/nutrition-toolkit Scroll down to the bottom and you’ll find the link to selecting the best food for your pet.

Sadly what I have found is that foods that are rated 5 star are often made by “marketing companies” by that I mean the company has little to no knowledge of nutrition but know how to make a food that people will buy. The founder of Blue Buffalo reports he got into dog food manufacturing because “ “Slap on a good label, come up with a slogan, and off you go,…..There were already a lot of smoke and mirrors in how pet food was advertised, and that was the sort of stuff we were good at.”

When you look at companies from a perspective of nutritional knowledge/ ingredient testing/ quality control which are the criteria veterinary nutritionists are using to measure a food’s quality a whole different perspective is gained.

So when a veterinary nutritionist was asked, “I have a 20 week old black lab. What is the best food to feed him?” Dr Remillard answered “I would suggest a Large breed growth food from either Purina, Hill’s or Royal Canin given there are no regulatory requirements for such a food but each of these companies have done and continue to do original research on preventing developmental bone disease in large breed dogs.”

General practice veterinarians often take recommendations from the specialists in their respective fields and so likely will recommend the foods that the specialists recommend.

Hope this helps to explain why veterinarians recommend the foods they do.

Dr Remillard’s website is petdiets dot com and there is question and answer forum you might find helpful. Dr Weeth has a blog at weethnutrtition dot wordpress dot com that has several general articles on food evaluation.
