Works! No fleas. I bought for four dogs and fleas are gone. We also don't have carpet, which I'm sure helps.

Best thing I've found! As a veterinarian, friends, family, and of course clients are always asking (or telling) me what the best thing for fleas/ticks is. We sell a lot of frontline and nexgard and I've used nexgard a lot in the past, but when I got my borzoi puppy this spring with all the parks, woods, fields we go to, he was coming home carrying many ticks that 6-7 hours later were still happily and lively crawling all over him. I don't even want them in my house so I switched to the Seresto collar which I had also used in the past. Now I don't even find ticks on him. I will be replacing it after 5 months because he swims, plays in the hose, has a doggy pool, and gets baths a lot and it depletes the drug from the skin so the collar runs out faster than the 8 months. To be safe if your dog has a similar lifestyle I'd recommend changing it after 5-6 months instead of 8 to be safe. Not any one product is always 100% in all areas and against all parasites. We are seeing increasing resistance in fleas and ticks and if you pet lives in a home that is utterly infested with fleas, yes any drug can be overwhelmed. With any product- oral, topical, or collar, watch your pet closely for the first 24-48 hours- symptoms of a rare unique adverse reaction can include GI upset, neurologic signs, or with topicals/collars- a local skin reaction like severe itch ,redness, hair loss etc. Seek care immediately and ensure it gets reported! My top picks for dogs are Seresto and nexgard (which can be used together) and for cats- seresto and cheristin (cheristin only does fleas).

Flea eliminated in 2-3 days soft rubber collar that some how repels fleas definitely get make sure your house is rid of fleas vaccum and wash your dogs bedding

Hands down amazing…… the scratching decreased by 80% in the first 24 hrs….. baby girl was so tired from days and nights of itching that she slept like a log and snored like a lumber jack the second night of wearing the collar!!! The fleas have definitely left this building!!! And the collar has secured prices to prevent the extra length from distracting your dog and causing her to take it off

I do tracking and trailing with my dogs, which means they get tons of ticks. I was picking off at least 10 per day when we were working. And I switched to the seresto from other products and I haven’t pulled off any ticks since. I love how long lasting these are, replacing every 8 or so months, they are water proof and go in the water with my dogs, and fit each dog well. I haven’t noticed any hair loss or smell with it. And my dogs don’t mind the collar. In the photo they are both wearing a seresto. the dog on the right, you can see where it flips over, which you can generically cut off.
