It would also be nice if you could share these studies that back up those foods.
The funny thing is that the studies come from the dog food companies. Sorry to say with out an independent study I would not believe the result. The dog food companies can say anything they want. There is no one to police these companies. I feed the most wholesome diet I can and in the past added glucosamine to the diet when needed. Why feed inferior food when you can just add what is needed to a quality food. Can you believe this is who we have looking after our dogs best interest.
Dog Feeding Trials done by AAFCO
In this method, the product (or a similar product made by the same company) is tested in dogs, under AAFCO guidelines, to ensure it provides adequate nutritional levels.
If it meets the profile, you will find the following AAFCO statement on the dog food label:
"Animal feeding tests using AAFCO procedures substantiate that (name of product) provides complete and balanced nutrition for (specific life stage)."
The labels on many commercial dog food brands will proclaim to contain a nutritionally adequate dog food diet, by passing "stringent testing as required by AAFCO."
However! ... Read on ...
A minimum of only eight dogs are required for the tests.
The tests run for a six month period.
During the duration of the test, 25% of the animals can be removed for varying reasons, and
It is permissible for the remaining dogs to lose up to 15% of their starting body weight.
Now, based on the above, what conclusions can we draw as to the "stringency"(?!!) of this testing, and the value of this AAFCO statement?
Considering only six to eight dogs ate these particular dog food ingredients for six months and survived with no more than an "acceptable" 15% loss of body weight!?
We wonder how many dog owners would consider it "acceptable" for their 30 lb pooch to lose 4.5 lbs in six months?
Kind of like letting the fox guard the hen house.
AAFCO advisors and committee members include representatives from major feed manufacturers and ingredient suppliers such as Nestle Purina, Hills Pet Nutrition, Nutro Products and Cargill Animal Nutrition. Despite this, AAFCO claims that its function is to protect the consumer. Despite its regulations, AAFCO has no means of enforcement, nor do they perform any analytical testing of foods. Regardless, AAFCO’s regulations are adopted by most states and are the standard to which pet and livestock feed manufacturers must adhere.
