The products from ProDen, especially those with the Plaque off formula, are excellent. They provide a natural way to maintain good oral hygiene for dogs and cats. I use both the powder and the bones, and my dog loves them. However, my only complaint is that they are not as hard as I would like them to be. Even my small-sized dog can easily break and eat them quickly. This is not ideal because the purpose is for them to chew and clean their teeth through friction. I would also like to add that the price is excessive for what you get. A box of Plaque off powder costs 20 euros (sometimes you can find it for 19 or 18), and it lasts for 5 months with daily use. The specific bones cost 17 euros, and you get 13 pieces. I believe it's unnecessary to explain why it's not cost-effective.

Edit 22/10/21: Nowhere in my review do I mention that I am unaware of the ingredients or the mode of action of the product. I know quite a bit about what I give to my dog as I am a veterinary assistant. I didn't write anything negative about the formula and ingredients in my review. I simply stated that the bones, specifically, are not suitable for me and my dog. I give the powder every day with his food, and it does help.

The bones, as we can see here: ProDen PlaqueOff® Dental Bones are a natural dietary supplement that contains the unique composition of ProDen PlaqueOff® powder. With daily use, this product ensures good oral and dental hygiene for your dog. Their unique shape and abrasive action help remove plaque and tartar while providing fresh breath.

The product should also work through friction. However, as I mentioned, even with a 7-kilogram dog, the bone was consumed in less than 2 minutes. As you can understand, there is no time within 2 minutes to remove any plaque or tartar. I don't see a reason why I should use this specific product when I can simply stick to the powder, combined with cleaning at home, deer antlers, chew toys, and daily brushing with coconut oil or dog toothpaste.

Lastly, we are not talking about a medicinal product. The product does not contain any medication. It is completely herbal.
