Why isn't my Seresto collar working anymore to control fleas and ticks on my dog?

I've been using a Seresto collar on my dog to keep fleas and ticks at bay, and it's been effective until recently. Over the past few days, I've noticed him scratching and even found a few fleas on him. The collar is still within its usage window, so I'm puzzled as to why it's not working anymore. Could there be a reason for this change, or should I consider trying a different method of flea and tick prevention?

Answer

If you've noticed that your Seresto collar isn't working as effectively as it used to, several factors might be at play. Let's explore some common reasons and potential solutions to keep your pet flea-free.

  • Check if the collar is fitted correctly—it should be snug but not too tight.
  • Ensure the collar is clean and not clogged with dirt or debris.
  • Consider whether there might be a heavy flea infestation in your environment.
  • Verify the expiration date of the collar and ensure it hasn't worn off early.
  • Consult your veterinarian to explore alternative flea and tick prevention methods.

It's important to address flea and tick issues promptly because these parasites can cause discomfort and transmit serious illnesses to pets. Ensuring your flea and tick prevention method is still effective will help keep your pet healthy and comfortable.
