I REALLY wanted the plaque vaccine to pan out. When it came out, my vets (who are cautious) said to wait a couple of years. Well, it has been found safe, but they discontinued it as it doesn't work. I really need a miracle. Though the truth is, she is good about it now and heck, I spent more time grooming the chow 2x a week than I do brushing her teeth every night. I still have to get them cleaned every 3 mos though. My vet recommended trying a water pik. ROFLMAO, me and what army? Sigh. So we just keep getting them cleaned. For the record, she isn't forming tartar, it is the actual plaque her gums react to.
