Garlic is one of the strongest medicinal plants on earth.
It contains over 80 different sulfur compounds, making it
a powerful infection fi ghter capable of killing all bacteria,
viruses and fungus on contact. Garlic also contains allicin,
one of the strongest disease and infection fi ghters found
in nature. It is an extremely effective and powerful broadspectrum
antibiotic, which means it kills all types of bacteria,
both gram positive and gram negative. It destroys the various
viruses that cause upper respiratory infections and infl uenza,
the ones that antibiotics are useless against. In fact, just the
odor has proven to be highly antibacterial. Unlike antibiotics,
however, it doesn’t harm benefi cial bacteria and fl ora, which
is very important to a rabbit’s system. When using garlic for
its antibiotic properties, be sure to use the chopped garlic
or fresh garlic juice within three hours or use a high quality
garlic extract. In general, rabbits dislike garlic intensely, so if
you need to use it, add a drop or two of the juice or tincture
to other herbal preparations, giving it fi ve times a day in
serious cases.

http://www.medirabbit.com/EN/Food/Food_main.htm  Click on topic that says  "TOXIC TO RABBITS"  and it brings up a PDF file that shows garlic in the toxic category.

I've also included a PDF attachment from the ASPCA Poison Control - you'll need to scroll down to see the information about garlic.  It includes cats and dogs with small animals reactions

I only got two responses on Etherbun.  One said most likely no good, while the other didn't know for sure and was in the same boat I am with information stating both good and bad.   I'll keep you updated with what I find out from other resources.

Okay, Poopy, I finally have an update on garlic.   After researching and researching it's the dose that is extremely important - that will draw the line between safe and toxic.

My rabbit savvy vet responded to my question about garlic with this answer: "The veterinary herbalists generally consider garlic safe, but caution not to overdo the dose. No safe dose has been established. An herbalist I trust says you can start dogs at 1 clove per 40# in dogs or 10-30 mg/lb of Kyolic brand. I would start at half of this dose (1/8^th clove or 40 mg of Kyolic for a medium rabbit) and work up, watching for anemia or GI upset."

So Poopy that's what I could basically come up with so far.  It is extremely important to note that even though the vets answer gives a general guideline, obviously if you, I or anyone chooses to give garlic to our bunnies we are doing so at our own risk.
