Delivery in perfect time and the product was well packaged. I worked with the dogs to get them used to my hands in their mouth but i can tell for sure that this toothpaste makes the things easier. The instructions are clear and good to follow, for the first time just put some product on your finger and let they smell it, taste it. I waited at least one hour to see if they were having any sort of reaction, but they seemed to really appreciate it and got all excited. I like the finger brush for my little jack russel/chi puppy. I just apply some toothpaste on it and then i start to work on the teeth (especially the canine), the dog licks it very happily, so it's really easy. The second brush works great for my small/medium manchester terrier and she loves the taste very much too. I didn't notice changes on the stools since i use it, which makes me really happy. Now, when i show them the toothbrushes and the toothpaste, they sit and look at me with big eyes, licking their mouths.I am so happy i found this product and for the quality, the delivery and the good time i am having with my pets, it's a great deal.
