I've used Sierra for my dog(s) heart worm & Seresto flea & tick collar for several years. Initially, as a pharmacist, I was concerned about the quality & safety of products manufactured outside the US. When I learned that theses Australian produced/sourced meds have similar US standards I've since had confidence in quality & satisfied with Sierra

WE have bought Seresto cat and dog collars from Sierra for the last 3 years. We have never had any problems with the collars, shipping and the prices are the best we can find. As long as we have pets we will get our collars here.
