OMW, if it cost 500 to do teeth here i"d be in horrible trouble. Fortunately even with blood work it is only $250, which I do once a year. The same vet with no blood work is about $150. I alternate with a local cheaper vet who is only 75 including antibiotics.. . so I only pay $550 a year for 4 full cleaning under anesthesia! I also have Arwen scheduled for Feb to take advantage of the dental month discount– sorry I didn't even think about mentioning that!
On the Plaque, I actually POSTED their study the first time I read about it. Will see if I can find it again.
Going to shoot myself, I hit post and lost about 30 mins of work.
Okay not going to do it again...
I found studies and in fact their own chart showing the plaque increased after 5 weeks.

But in HUMANS it continued to drop with, although (page 5,) it also said main improvement the first 5 wks. Bleeding decreased continually so obviously helping some even if not plaque after the 5 wks. Some significant differences in control group and PO with pH being much lower. They said higher could cause stones so that is good, but the TRUTH is you want NORMAL urine pH, not low or high. But the blood work was all normal for both groups so not really worried.

So some mixed stuff, but if it helps some, why not? If it helps with bleeding, it must be doing SOMETHING good, so why not. And since even humans are using it, and it is basically seaweed, why the heck not? I may order some more.
