Fill your dogs dish with an extra fiber supplement that is wholesome and nutritious as it is delicious. Due to fibers ability to absorb water, it helps bulk up stools and slows down the time it takes for you to excrete waste. Increasing this type of fiber in your diet can help to reduce diarrhea or help to bulk up loose stools. Soluble fiber also slows the absorption of glucose (sugar) into our bodies, minimizing the spike in blood sugar in our bodies after a meal, helping to better regulate our blood.
