Hey Robyn,
Renal failure? That's atypical, and I'd guess not due to the garlic. If an animal is going to get ill on garlic, it's Heinz Body Anemia, a red blood cell oxidation disorder, as I recall.
I changed my ways with garlic since reading what looked to be a well done study on garlic and dogs from Dogs Naturally Magazine. See if you can search it out and let me know what you think.
