02 Mar My Dog Licked Glyphosate Sprayed Weeds
The Animal Poisons Helpline is often contacted regarding pets that have chewed on or walked over weeds that have recently been treated with glyphosate.
Glyphosate is a non-selective herbicide that is commonly used throughout Australia and New Zealand and can be purchased from most hardware and grocery stores. Glyphosate is available in many different preparations, ranging from dilute ready to spray products (typically less than 1-2% glyphosate) to concentrates that require dilution prior to use (typically 36% but some agricultural products may contain up to 80%). Some weed spray products contain a combination of glyphosate mixed with other herbicides.
Pets that lick or eat small quantities of recently treated plant material are unlikely to develop any signs other than mild gastrointestinal upset. Glyphosate is also poorly absorbed through the skin and pets that walk over recently treated areas are unlikely to develop anything other than mild irritation of the exposed areas. Pets that have access to larger quantities of glyphosate solution, particularly the concentrated products, can be at risk of more severe and potentially life-threatening effects.
To reduce the risk of poisoning from glyphosate, keep pets away whilst spraying and ensure they are kept off treated areas until they are thoroughly dry. Most importantly, always ensure that all primary packaging is stored well out of reach of pets. As concentrated products (those that require dilution prior to spraying) are particularly dangerous, it may be best to avoid storing such products in your house where possible.
The Animal Poisons Helpline is free to all pet owners in Australia and New Zealand. If you are concerned your pet may have been exposed to a poison, phone 1300 869 738 (AU) or 0800 869 738 (NZ) for advice, even if your pet looks well.
