There might already be a thread about this...BUT..did any of you guys hear about the new vaccine by Pfizer, it is to prevent the bacteria from growing on dogs teeth..this in turn will prevent periodontal disease..It is $25 each time...it has to be given a total of two times, three weeks apart. It seems kind of interesting..I suppose just one more preventative measure to keep the teeth clean. It might be something to look into considering that teeth are a major problem in basically all dogs over the age of three.. hmm..dunno....
