Query: Use caution with this product

While the product does work, be aware that Tylosin is actually a low grade antibiotic. After 2 weeks of use, both my Bichons developed diarhea - and that is when I discovered what Tylosin really is. Use of a daily antibiotic can kill the "good" intestinal bacteria and cause other problems. If you are planning on using this product, consult your veternarian first and use with caution!
