I use this product and brush as well. I feel that this product is good on its own but even better when added along with brushing. If your pooch doesn't like brushing then this is a good option as far as getting used to the spray...I think it is all in how it is approached. It needs to be done as matter of factly and then rewarded with words and enthusiasm. I use on 3 dogs in my home and none of them have an issue with it. I have seen a huge improvement in all the dogs teeth and breath :)
Yes, it does work. My dog has disgusting chronic halitosis and this definitely helps. It was recommended by our vet and several friends so I thought it was worth a try. The price is good and the length between doses makes this a quality product.
It is a spray. It wont do much. For a comparison, it would be like you never brushing your teeth, but using mouth wash once in awhile. You're better off having them cleaned professionally and brushing with canine toothpaste at home for upkeep.
Take your pets to the vet at least annually for a dental prophalaxis. oral health is extremely important in preventing major problems down the road. Talk to your vet and see what they recommend to use on a routine basis.
