I love the idea of Hartz Breath Strips. It is something that I definitely wanted to try. Because as much as I love my dog a just cannot stomach doggie breath. It is just the worst! So I was excited to see this product and grabbed it off of the store shelf. The problem started when I tried to give the breath strip to my dog. These are very much like the breath strips for humans in that they dissolve upon putting them in their mouth. The issue for me was getting it in my dogs mouth. He wasn't impressed with the smell of the breath strip so he didn't try to eat it. So I then had to try to get this in my dog's mouth. It became a little messy hen I attempted this because once it gets wet with saliva it gets slimy and messy. Fortunately my dog didn't put up much of a fight and did let me get it in his mouth. That being said they definitely made his breath fresher! It knocked that doggie breath out. So I'd say it may be worth the battle. Quality of Ingredients Contains things like mint and parsley. Side Effects No side effects whatsoever for my dog.
