We have 3 dogs and one cat that wear this collar, the only one we use. I’ve used them for years and they work. We live on 5 acres so the dogs are outside a lot and the cat is mostly outside. Never had any fleas. Once or twice I’ve found a tick on the small dogs but I check them regularly and removed them right away so I don’t know if they would have died if left alone. I recommend this product. Initially it seems like it’s costly but if you break it down over 8 months it’s very cost effective and it works. No need to worry about applying every month.
