Anti-flea and tick treatments for dogs could be harming sensitive streams and ponds in the New Forest, conservationists have warned.

A study by Wild New Forest and the Freshwater Habitats Trust showed high levels of imidacloprid, found in spot-on treatments, at four locations.

Previous research found it negatively affected insect species.

The National Office of Animal Health, which represents the veterinary pharmaceuticals industry, said parasite control products were "essential in helping pets live longer, healthier, and more active lives".

It also said "decades of evidence around the world demonstrates the safety of these products when used according to label directions" and that "the quantities used in pet parasiticides cannot explain levels of the compounds detected in some waterways. These compounds have multiple other uses."
