This being said about AAFCO, Hills Science Diet, and Iams Inc hire Veterinary Nutritionists on staff to help design, perfect, and produce high quality foods that are healthy for companion animals. None of the other companies do. As wonderful as some of the other foods sound, none of their ingredients or label claims are unsubstantiated by veterinarians.AAFCO’s main responsibilities are to regulate label text and product names. Because it is a private organization, pet food companies do not have to comply with these standards if they don’t want to and AAFCO has no enforcement authority. Interestingly, each state can set pet food manufacturing guidelines that must be adhered to for that state. Alaska and Florida have no guidelines for pet foods produced in their states.
AAFCO was formed in 1974 because the industry found NRC’s regulations to be too restrictive and created its own procedures for claiming nutritional adequacy in pet foods. They also decided that instead of lengthy feeding trials, chemical nutritional analysis would be conducted to determine minimum nutritional requirements.
Stomach upset from food switches often occur when they are done quickly. I've never had a problem switching foods with my dogs, but some are more sensetive than others. You also have to be aware of what protein sources are in the foods, as many dogs have an allergy to different meats which can cause upset as well.chimom said:I'm really glad to read some of these comments. I have been feeding Royal Canin for a while now, but Jasmine has begun to get tired of it, and was thinking about switching to Science Diet or Wellness. However, I had some reservations as I keep reading it's not good to switch dog foods very often as it can sometimes cause stomach upset.
If I understand Nate's post correctly, it is O.K. to switch brands occasionally? Or is this only for adult dogs? Jasmine is 9 months old now, and I was considering switching her to an adult food in a month or so. Is this too soon to switch? As of her last vet visit, she is very healthy and thus far we've had no problems with stomach upsets, diarhea, etc. and no weight problems.
