Flea and Tick Collar for Dog, Natural and Safe Flea and Tick Collar for Large Dogs, 2×8 Months Protection, Waterproof, One Size Fits All, Charity, 2-Pack

This is a great collar for animals! I bought this brand for my cats because they have sensitive skin and I liked them so much I bought them for the dogs too. Be advised, it does not KILL fleas or ticks, it simply repels them. We used it with another topical flea medicine when we had a huge outbreak and these collars had no odor, caused no reactions and kept repelling the bugs! Will order again.

This is wonderful we have tried everything, no bugs of any kind land on my dogs. Well worth it. All natural ingredients so doesn’t harm dogs.

Without chemicals, it seems to be safe for my pets. Flea and tick season hasn't kicked in yet, so I'm not sure about effectiveness this year; however, I used them last year, and not a single flea or tick, so it seems to have been effective. I've used these on cats and dogs, and can report no skin issues. Easy to use, and the collars are very durable.

I love these collars! They seem to work very well. We had ticks bad. My husband got lymes disease. We think the ticks were coming in on the dogs so we got the collars for all 3 of them. Haven’t seen a tick in the two months since. And they smell good! Unlike the collars that say, do not sleep with your dog with his collar on. I highly recommend.

The collars were great, haven't had a single flea or tick on the dogs since I got them in April. Only issue is it's now June and the collars don't smell like essential oils at all anymore. I'm not sure they work anymore since they don't smell.Said they work for 8 months. But it seems they only work for 3.
