The Seresto collar for large dogs (those over 18 pounds) is generally considered effective for keeping fleas and ticks at bay for up to eight months. But like with anything, there are some things to keep in mind that might affect how well it works. According to the manufacturer and our research, most dogs do get nearly the full eight months of protection, which is pretty solid.

A great thing about this collar is that it's water-resistant, so it should hold up through rain, sunlight, and the occasional bath or swim. Just be aware, if your dog is a frequent swimmer, the collar's effectiveness might drop off a bit earlier—like five months for fleas and seven for ticks.

Keep in mind that not everyone has the same success with these collars. Some folks notice that it doesn’t seem to work as long as expected. This can happen if it's not fitted right or if it's exposed to water constantly. There are also fake collars out there, so make sure you’re buying from a reliable source.

Also, watch out for any irritation or allergic reactions. Every dog is different, so keep an eye on any changes after you put the collar on.

If you're not getting the protection you expected, check the collar’s fit, how much it's been exposed to the elements, or whether it's a genuine product.

Overall, using the collar properly and buying from a trustworthy place will give you the best chance of making it work. It's generally got a good track record, but everyone's experience can be a bit different.
