Our almost 10 year old rescue, Bailey, since getting older, has struggled with, what has now been diagnosed with stress colitis. She originally had problems with constipation, and would really struggle. Then when she had any “stressful” situation, such as travel, or change in routine, she would struggle with diarrhea, and even bloody stools. I was fortunate to find Bernie’s Perfect Poop, and it has made all the difference, and even though she’s a bit of a picky eater (ok, maybe I created a diva), she LOVES Bernie’s chicken flavor. I just sprinkle it on food, and she gobbles it up. So grateful for this product.
