My dogs (9, 7.5, and 3.5 yrs. old) do have some buildup on their teeth -- the canines, mostly, and a few random icky spots here and there on the old boys. Ollie, in fact, is slated for a full dental cleaning (and lipoma removal) in July, but that will be his first and probably last cleaning for his lifetime. Lilly's, on the other hand, are pretty much spotless.
I've used Petz Life gel on my dogs and cats and it does work. I just got lazy about doing it with the cats since they absolutely hated it.
Apparently it's now available through Petsmart.
