Don't let your dog swim after a flea treatment

Clean and healthy water is essential for people, animals, and nature. Dog owners also play a role in this. After all, what we give our pets can end up in the water without us realizing it. A good example of this is the use of flea treatments.

Why shouldn't you let your dog swim after a flea treatment?

Many flea treatments for dogs, especially the popular spot-on drops, contain pesticides such as fipronil and imidacloprid. Research shows that dogs can release these substances into the water through their skin and fur, even up to 28 days after treatment.

When a dog swims in a ditch, pond, or river, these substances can end up directly in the surface water. This is a problem because:

  • the substances are toxic to aquatic insects;
  • they harm aquatic plants and birds;
  • and they disrupt natural ecosystems.

This leads to a decline in biodiversity and a deterioration in water quality.

How long should you wait before letting your dog swim again?

Do not let your dog swim for at least two days after applying a flea treatment. This will reduce the chance of the treatment ending up directly in the water.

Please note: some products may continue to release substances even after this period. Therefore, always check the package insert and make an informed choice.

More environmentally friendly alternatives to flea treatments

Good news: there are more and more options for controlling fleas without harming the environment.

Natural flea remedies

These products are often based on plant extracts or natural substances, such as:

  • lavender;
  • citronella;
  • eucalyptus;
  • apple cider vinegar;
  • coconut oil;
  • diatomaceous earth.

They keep fleas away without using harsh pesticides and pose less of a risk to water and the environment.

Botanical, scientifically-based treatments

Some products effectively combine natural ingredients. They:

  • do not leave toxic residues in water;
  • are biodegradable;
  • and are safe for other animals and the environment.

By using flea treatments responsibly and taking your dog’s swimming habits into account, you can help keep our waters cleaner and our natural environment healthier.
