Bests & Worsts Reviews from Amazon

This seems like a really great formula, but what I didn't notice is that it contains yeast. My dog has severe environmental allergies from May through September, and one of the symptoms is an increase in yeast in his system. I gave him four servings of this (one pill cut in half twice a day, so two days.) Both evenings he had a reaction--he is a pug, so it was a respiratory reaction. I had been giving him a different high quality brand joint supplement, which seemed to be working 'Ok.' However, it seems that he is having arthritic discomfort, so I decided to give this a try since it contains nature's aspirin, white willow bark extract. This would be a perfect formula without the yeast. Doesn't matter if it's Brewer's yeast, it is still yeast, and to a dog that has yeast issues, this is not good.
