VeggieDent??

Has anyone tried these? They came up on my amazon recomendation page and I was wondering if Izzy would be able to use them since they don't contain beef.

Here are the ingredients:

Corn starch, Glycerin, Soya proteins, Rice
flour, Palatable agent (saccharomyces
cerevisiae), sorbitol, corn derivatives, water,
potassium sorbate, chlorhexidine digluconate

I wouldn't give them to my dogs given the high grain content and the as yet unknown ingredients. Off to google the "palatable agent"

Saccharomyces cerevisiae is a species of budding yeast. It is perhaps the most useful yeast owing to its use since ancient times in baking and brewing.
It is believed that it was originally isolated from the skins of grapes
(one can see the yeast as a component of the thin white film on the
skins of some dark-colored fruits such as plums; it exists among the waxes of the cuticle). It is one of the most intensively studied eukaryotic model organisms in molecular and cell biology, much like Escherichia coli as the model prokaryote. It is the microorganism behind the most common type of fermentation. S. cerevisiae cells are round to ovoid, 5–10 micrometres in diameter. It reproduces by a division process known as budding.
Many proteins important in human biology were first discovered by studying their homologs in yeast; these proteins include cell cycle proteins, signaling proteins, and protein-processing enzymes. The petite mutation in S. cerevisiae is of particular interest.
Antibodies against S. cerevisiae are found in 60–70% of patients with Crohn's disease and 10–15% of patients with ulcerative colitis.
"Saccharomyces" derives from Latinized Greek and means "sugar mold" or "sugar fungus", saccharo- being the combining form "sugar-" and myces being "fungus". cerevisiae comes from Latin and means "of beer". Other names for the organism are:

• S. cerevisiae short form of the scientific name
  
• Brewer's yeast though other species are also used in brewing
  
• Ale yeast
  
• Top-fermenting yeast
  
• Baker's yeast
  
• Budding yeast
  

In a word: YUCKO

What is Sorbitol?
The other name of sorbitol is ‘glucitol’. It is actually a sugar
alcohol, which is slowly metabolized by the human body. Sorbitol occurs
naturally in many stone fruits and berries of trees, which belong to
the genus ‘Sorbus’. It derives its name from Sorbus. Now let's focus on
the usage of sorbitol.

This is sugar, basically. And it has some side effects--diarrhea being one of them--in humans.

You're right, the ingredients don't sound great. Darn it I was hoping I found something I could use for Izzy. Guess I need to keep trying to brush her teeth.
