When pets treated with topical flea and tick preventatives go swimming or are bathed, the chemicals can wash off into water systems either directly or via our sewage systems. This runoff can contaminate rivers, lakes, and oceans, harming aquatic life like fish, nymphs and algae.
Indeed, a recent study found fipronil (a spot-on treatment) in 98% of freshwater samples in the UK, and are reaching concentrations known to harm aquatic life in urban areas. It’s not just our pets swimming though, researchers believe that some of this results from handwashing after handling our pets, or simply bathing our pets, with wastewater entering the sewage network.
- Did you know that your dog should not be allowed to swim for 2 weeks after having a topical treatment?
- Did you know you shouldn’t touch your dog on the site where the treatment was applied for 24 hours?
