The gel may be applied a number of ways. If your dog will allow you use a tooth brush or one of those finger brushes, that is the most desireable, because it will accelerate the process of tartar and plaque removal. However, if you have a dog that will not allow that or it's mouth is too small for a brush, all you have to do is get it into the mouth.
For example my Rottweiler bit the toothbrush in half so I just put a tiny smear of peanut butter on her dish and squirted the gel on top of it. She would lick through anything to taste the peanut butter. Then I just keep her water away for a half hour or so. I found doing it at night, at bed time was the most effective, because of the low activity level then. It took me about a month and a little over one bottle of gel bring her teeth back to beautiful. To quote my vet,"she has the teeth of a 2 year old". Now, bear in mind, she is over 9 years old. Also remember this product removes tartar and plaque, it is not a bleach. There may still be some stains left, but these are inconsequential. This all natural product also kills of the bacteria that turn the plaque into tartar as well as the bacteria that cause gingivitis. Consequently, you will probably see an increased activity level from the new feeling of "well-being", now that your dog no longer has those horrible toxins going into it's system.
