You know only a few companies recommend this rotation of food; I'm not convinced it's a good idea. The general consensus among vets seems to be to find a good food and stick with it. I know many of you don't think vets know anything in the area of nutrition, but the safest method is sticking to what works, and don't change unless there is scientific evidence that it's better to rotate. Human studies have shown the healthiest people have the most limited diets, and eat the same thing every day. When a new food is introduced, dogs are even more prone to stomach upsets than humans. If the information you're getting is from dog food companies and the people who sell the food, I would be very leery. I would avoid any company who says that when dogs eat their food they might purge because they are getting rid of all the toxins from their old food. This is such nonsense, and I can't believe how many people accept this. |
