We have been using this product for quite sometime now and I really think it has helped the condition of their teeth. Thing to remember when using the gel (which is what I use...more than the spray), is to pick up the water and make sure they haven't eaten anything within the last half hour. The directions say it works best if the dogs don't eat or drink anything for a half an hour before or after brushing their teeth with the product.

This along with chewing bones have really improved all of my hounds teeth.

Pros: Dogs seem to like it and it is easy to use.

Cons: A little Pricey, but....less than a dental.

My holistic vet recommended this product to prevent my dogs from developing tartar. Apparently you can use it as a preventative method as well as a treatment. It works really well.

Pros: Easy, clean

Cons: none

Noted decrease in bad breath of one canine and improved gingivitis for one feline.

Pros: Decrease bacteria

Cons: Product safety always a concern for us
