ProDen PlaqueOff Powder for Pets - Cat & Dog Breath...

Most Helpful Review

"We have used this product in our 3 yo greyhound's food for over a year (along with brushing her teeth regularly, and taking her in for her yearly dental cleaning), but have noticed no difference in the amount of build-up on her teeth or in her bad breath. We followed the directions for a dog her size (she's 65lbs), and used two scoops a day in her food. As other reviewers have stated, greyhounds have notoriously bad breath and dental problems, so maybe that could account for the product's ineffectiveness?But that's not even my biggest complaint with this product.My biggest issue is that I believe this product caused excessive shedding, dandruff, and other hypothyroid-like symptoms in my greyhound. The breed typically has low thyroid function already, and there is debate on whether or not it should be treated with medication. Unfortunately, our girl was shedding so excessively that she was beginning to bald all over her body (not just the hind quarters). Her belly also went from being pink to a near black color. I took her into the vet, tested her for hypothyroidism, and her t4 levels came back extremely low -- even for a greyhound -- and we had to start her on a synthetic hormone. She was only 2 yos at the time of this diagnosis, which is extremely young for a dog to already be treated for under active thyroid.She was on the synthetic hormone for 7 months, and there was no difference in her shedding, dandruff, or the color of her stomach. In fact, it worsened. Two months ago, I took her back in for more testing. It appeared the synthetic hormone was working, so there shouldn't be any reason for her continued symptoms. The vet was actually concerned that increasing her dosage would shift her into hyPERthyroidism based on her blood panel results.I did some reading and decided to stop giving her PlaqueOff. She has now been off of it for a month. Within two weeks, her stomach changed back to her normal pink color, she is not only NOT shedding, but her coat is shiny and growing back in, and there is NO dry skin or dandruff.I can't prove this product caused hypothyroidism or hypothyroid-like symptoms in my greyhound, but I can tell you that enough improved once I removed PlaqueOff from her food, that I'm beginning to wonder if she even truly has an under active thyroid. I plan on taking her into the vet soon to talk about this and possibly have more t4 panels taken.Another side note: Our greyhound has also routinely had issues with diarrhea and extremely soft stools. We tried feeding her Kirkland's Signature grain-free dog food -- bouts of diarrhea continued. Then we tried Taste of the Wild - bouts of diarrhea continued. Merrick -- bouts of diarrhea continued. Finally, after we stopped giving her off PlaqueOff she has healthy stools.I hope this isn't a common problem, but if it is, I hope this review helps anyone else who is experiencing similar symptoms in their dog."
