About this product
Tell uninvited to guests to “bug off” with the Hartz UltraGuard Plus Reflect-X Flea & Tick Collar for Large Dogs. A convenient alternative to topical flea applications, this collar starts working fast to kill and repel fleas and ticks. It also prevents flea eggs from hatching, which stops the flea cycle by preventing re-infestation. And as an added bonus, the Reflect-X shield reflects direct light for up to 300 feet, which is great for adding some visibility and safety to nighttime walks. The best part? It works for seven long months, so you can go worry-free for more than half a year.
