y golden is picky but loves these. I noticed a considerable difference in her teeth and the amount of tartar she has on them, especially her back teeth which were if I'm honest were pretty disgusting... She wiggles too much to brush her teeth with a brush and her teeth are too big for it to even help reduce the tartar. I tried these when they were 50% off the first time and I've bought more since at a regular price because they ACTUALLY work! I'm stoked on this product and her teeth have never looked better, her vet agrees! These treats are 100 % vegetarian, Gluten free which makes them perfectly healthy to consume whenever you think is best.
