Hi AC,
I use Lifeway low fat plain kefir that I buy in my grocery store.(I drink it as well as giving to my girls.) Lifeway does not have any added sugar but milk has natural sugars so I seriously doubt that you can find sugar free kefir. When you consider the small amount of kefir that you would be giving your dog, the low amount of natural sugar should not be an issue.
