The Seresto Large Dog Flea & Tick Collar is supposed to keep fleas and ticks away for up to 8 months, at least according to the manufacturer. It's a convenient way to help protect your dog from those annoying pests. However, how long it actually lasts can vary.

The manufacturer's description mentions that the collar is water-resistant, which is great if your dog loves swimming or needs frequent baths. That said, if your pup is a regular swimmer or gets more than one bath a month, you might see the protection last around 5 months for fleas and about 7 months for ticks. So, if your dog spends a lot of time in the water, the collar might not last the full 8 months.

From what we've gathered, there are mixed feelings about the collar's effectiveness. Many dog owners say it works for the full 8 months, but some notice it doesn't work as well after a few months, especially if their dog swims a lot. To get the best results, make sure to stick to the care instructions.

If you're finding it doesn't last as long as hoped, consider checking things like how often your dog's getting wet. And if you're still having trouble with fleas or ticks before the 8 months are up, it might be worth chatting with your vet to see if anything else could be affecting the collar's performance.

Overall, the Seresto collar usually does its job for up to 8 months, but keeping tabs on your dog’s activities and sticking to the guidelines can help.

Always watch for any signs of fleas or ticks and talk to your vet if you're worried about your dog's health or the collar's effectiveness.
