NexGard Spectra

This product works so great for my German Shepherd! Have never seen a tick, flea or any other bug since I started using this a few years ago, not to mention negative annual heartworm test results. Highly recommend the product and bestvetcare! Standard shipping is always done within a very reasonable time frame.
