I put the Seresto Flea Collar on all my animals & did not initially notice any improvement as they were all still scratching & I was still getting bit. In addition to the flea collars I also purchased a number of other products including multiple frequency plug-ins, flea sprays, flea lights with sticky paper, ACV & aluminum free baking powder & baking soda etc. Additionally, significant cleaning & washing of bedding etc was done. With all these measures, the situation has significantly improved. This year the flea situation seems to be especially bad & while I think the flea collars help, they need to be part of a more comprehensive plan in order to see results.

Dog doesn’t mind it and it saves me stress

Quite frankly my 1 1/2 year old 100lbs Rottweiler is a menace to herself and society. If given the opportunity to choose violence and near death experiences (such as eating a bag of screws, glass, swallowing socks whole, carrying 12” kitchen knives around the house, etc.) that will always be the choice she chooses. I was concerned she would try to hang herself somehow on the collar but she never has and doesn’t even notice or care that she has it on. 10/10 recommend it saves a lot of stress not having to worry about putting the liquid flew meds on.

We have ticks in the summertime, last year my dogs were on pills for fleas & ticks, so the stinking bugs would hitchhike into my house on the dogs. My dog trainer said she had the same problem & started using seresto & things changed. Boy was she right! The ticks stay off my dogs & don’t use them as a taxi to get into the house now. I bought the collar that keeps the seresto collar contained to prevent my stinkers from losing these . Great investment! Will definitely use again next spring & summer!

We had a flea infestation in both our pups, these got rid of them fast. We had previously been using topical TX, and unfortunately still have to on our pug as he had a skin reaction to the collar. I honestly think having this on the one pup still helps prevent them on the other. We do still use topical on the pug.

Wouldn’t order again made the fur around my dogs neck and left a big area with rawness so I had to throw the used one away and donated the other one because I couldn’t use either one of them not worth chancing your pets safety and health just because the price is more affordable than the chews at the vets office

I used Soresto collars for my last dog, Kendall, who never had a flea after buying her first one. They work very nicely, and since putting it on Lady, I’ve only seen one flea, and that was still within the first 24 hours after application.

I always used flea/tick preventive pills for my dogs. But with my vet's recommendation, I tried Seresto. It does seem to be working. I take my dogs for runs in the mountains, mountain bike trails at parks, and various wooded trails. I haven't noticed fleas or ticks harming my dogs. They may get on my dogs and bite, but none of them are alive when I find them. I have only seen a few over a year that I actually pulled. But they were always dead. So it is working, I assume.

After recently, moving to an apartment complex for the first time with my dog, we were having a hard time. Dealing with fleas that we’re very stubborn. After many other unsuccessful products, the flea collar worked within 48 hours. My dog was visibly less, itchy, and after a few days, there were no more fleas. We’ll definitely use in the future.

My dogs both usually use these each year, however this year my older girl had an allergic reaction of some sort and couldn't continue to wear it for more than 30 minutes. She became extremely restless and uncomfortable. So she will be discontinuing use. My other dog however is fine with it and will remain using it for now.

Our long hair Chihuahua mix has had seizures off and on throughout his life and this was the first and best flea treatment we could find so we have stuck with it for years. It doesn't affect his health like other treatments we tried. It's convenient as well since it lasts for several months!
