Well I have help with the photos (my wife) and I have trained both dogs to like it.. I know that sounds impossible but its not. When we started I would put on hand on the bottom jaw and one around the top of the snout. I would say the command "open" while I pushed my thumb and index fingers on the bottom hand into the mouth. At first that was about as far as I got but I would then let go and praise them and give them treat. the female caught on quick but the male took a while longer. Since then they have started associating the Petzlife bottle with a treat and they now come right over when we get it out. Pretty amazing and yes it clears up the bad breath because it kills the bacteria that causes it.
Good Luck!
