I haven't really seen results yet, but my dog hasn't been on it for very long yet. We're just barely starting the 2nd jar. One thing I did like is that if you have a large breed dog, you guys send a bigger jar with the amount that a larger breed dog needs for an entire month, without charging more money just because they have to take more per day. Other companies I've dealt with, you have to buy 2 or 3 jars every month if you have a large breed, because their jars only have enough for small breeds per month, so you end up paying tripple the amount just because you have a big dog. I absolutely love that your company doesn't do that! I've also used the paw soother on my dogs paws for the last 5 or so years, and that stuff is awesome!!! She has allergies to grass, so her paw pads get so dried out and crack, and I'll put that on and massage it in to each paw pad really good, and by the next morning, her pads are completely healed and soft, and so pretty! I'm really hoping to get as good of results from this probiotic. I will update this review after my dog has been on it long enough to see results. It shows that your company truly does care about the health of our pets! I would have given 5 stars, but I'm waiting to see the results of this probiotic.
