@Kananga:
There was a local pet store nearby that carried PetzLife products. The employee there mentioned that he hears nothing but good things about this stuff and that they were completely out of the spray. $25-30 may seem like a lot for such a small amount of product but it's cheap insurance to keep your dogs teeth healthy.
$25 - $30 seems like pennies to me when you compare it to the cost of a full dental under anesthesia. I can't ever anticipate having to another dental on our Rat Terrier again, nor any dog we would get in the future. There is simply no tarter build up with this product when used daily, or even a couple of times a week.
Jack likes the taste too. At first he wasn't nuts about it, but it didn't take long for him to acquire it. He does not like the 'spray' in his mouth though. He's always been skiddish about a spray sound. If I had a pup I'd start in with the spray from the get go so they got used to the sound.
