For dogs, swimming is a great form of exercise and a way to keep cool during the warmer months, but it can create a problem for nature on the Heath. Dog flea and tick treatments contain powerful pesticides. Dogs that have recently been treated with flea and tick products can introduce these chemicals into ponds when they swim, where they can kill dragonflies and other pond life.
You can do several simple things to minimize the effect of these chemicals on our wildlife. The Heath & Hampstead Society has worked with veterinarians and other experts to provide advice on SAFE DOG SWIMMING. Please have a read, and consult with your veterinarian if you are uncertain about the products you use and how to use them.
Thank you!
