there are a few you can look at healthy mouth, petzlife and Leba III.
I agree with Gracielove. A raw meaty diet is best for your dogs teeth, there are no carbs to create plaque and tartar build up and the chewing motion actually pushes up into the gum line to clean the teeth. I've seen the results on my own dog.
My friend had a 6 year old yorkie with black plaque buildup on her teeth, she bought Leba and followed the instructions. She told me within two weeks it was falling off in chunks. |
