We found “oat fiber” in just over 2 % of dog foods.  A more generic search found that “oat” is used in almost 28% of dog foods.


Common benefits or risks of Oat Fiber

Oat fiber provides fiber, which helps move food through the digestive tract slowly, which further helps to optimize the absorption of nutrients.  Oat fiber can improve stool quality.

Oat fiber also is a source of protein.  One ounce of oats provides over 4 grams of protein.

Oat fiber is rich in vitamins, including thiamin and folate, and minerals including phosphorous, magnesium, and iron).

Consuming too much oat fiber can cause some problems, including a potential calcium deficiency (possible due to a calcium / phosphorous imbalance).

  9. We feed grain free foods, but I don’t have an issue with grains in treats because the dogs don’t get a lot of those. I think that ingredient may be more common in treats.
