I was recommended this product by a friend, to help with our Arab coughing during a dry, dusty spell. Having tried a couple of other products with little success, we introduced this product into his feed.
After an initial reluctance to eat it straight away, we left the food bucket and when we returned a few hours later he had eaten it. From then on he ate it happily. The result was that after about a week there was a noticeable reduction in coughing under work. I am now 3 weeks on, and it is still helping him considerably. On this basis I can definitely recommend giving it a try!
