I take probiotics everyday simply because they make me feel incredible. I have less bloating, am more energetic and overall a lot happier. After I saw this product on Facebook I bought a bottle for my German Shepherd Duke. He's always been in great shape and had no noticeable digestive issues but I figured after having had great experience myself with a product like this, maintaining a healthy gut flora could only be beneficial for him too. Just knowing that I'm doing everything I can to keep him healthy feels great and I didn't even expect to see any changes in him. Two weeks into his first bottle though he's even more active and more playful than before. He's always been on an omega 3 rich diet therefore his coat has always been in excellent condition but I almost want to say it's even more shiny now.
