Pet Oral Repair & Whitening Gel, Cat & Dog Dental Care, Toothbrushes, Teeth Cleaner & Fresher Breath, No Brushing, 3Pcs

I tried to used it on my dog but it didn’t work for my dog

Unfortunately, this does not work as described. I have done it three times and no change in my dogs teeth.

Some of the ingredients listed are for oral care like baking soda. The Gallnut extract, I've never heard of but I'm happy to see this gel pen has only 6 ingredients. I can't verify the effectiveness of this product, but I've used this type of gel pen before and as an applicator, it's very effective. The twist of the pen and small amounts goes through the brush that you can apply without much waste of the product. The other nice thing about these gel pens are refillable if you know how to take it apart. The brush applicator is one of the more easy way to apply product to teeth and for dogs teeth, I think it's safer for them as it's harder to apply too much product with the liquid flow control of these gel pens. This product is made in China.

Did not do a thing for my dog. Would not recommend.
