The collar is infused with two active ingredients, imidacloprid and flumethrin, which work together to kill and repel fleas and ticks for up to 8 months.

Why Choose Seresto Large Dog Vet-Recommended Flea?

As a pet owner, it’s important to choose products that are safe and effective for our furry friends. Seresto Large Dog Vet-Recommended Flea collar has several benefits that make it stand out from other flea collars on the market.

Vet-recommended: One of the top reasons to choose this flea collar is that it is recommended by veterinarians. This means that it has been tested and proven to be safe for dogs.

Long-lasting protection: The Seresto flea collar provides up to 8 months of continuous protection against fleas and ticks. This makes it convenient for pet owners who don’t want to constantly apply topical treatments or remember monthly doses.

Water-resistant: The collar remains effective even after exposure to water, so you don’t have to worry about constantly removing it when your dog goes swimming or gets wet.

No mess or smell: Unlike topical treatments, there is no greasy residue or strong odor with the Seresto flea collar.

Suitable for large dogs: This specific size of the Seresto flea collar is designed for dogs weighing over 18 pounds, making it perfect for larger breeds.

How Does It Work?

The active ingredients in the Seresto flea collar are released in low doses onto your dog’s skin and coat over time. These ingredients then spread through your dog’s natural oils, providing long-lasting protection against fleas and ticks.

Tips for Using Seresto Large Dog Vet-Recommended Flea

To ensure maximum effectiveness, here are some tips on how to use the Seresto flea collar properly:

  • Fully activate before use: Before putting the collar on your dog, make sure you fully activate it by stretching and pulling on both ends until there are no more white dots visible.
  • Tighten properly: The collar should be snug enough so that two fingers can fit between the dog’s neck and the collar. Make sure not to leave too much extra length as this may cause your dog to chew or get caught on something.
  • Maintain regular use: For continuous protection, make sure you replace the flea collar every 8 months or as recommended by your veterinarian.
  • Bathe your dog regularly: Bathing your dog once a month will not affect the effectiveness of the flea collar but may help keep their coat clean and healthy.
