Several local councils’ environmental initiatives to reduce grass cutting in public areas have been linked to an increase in grass seed-related infections among dogs. Campaigns such as No Mow May, which encourages leaving grass uncut during specific periods to support biodiversity, have resulted in grass growing as tall as knee height in certain parks and roadside verges.

Veterinary experts warn that allowing grass to grow unchecked creates conditions for grass seeds to loosen and attach to passing animals. These seeds, which have sharp edges, can penetrate deep into a dog’s skin, potentially causing abscesses, irritation, or abrasions. In some cases, if the seeds are inhaled, they can lead to more serious infections.

The No Mow May campaign, supported by various Green Party branches and championed by the conservation charity Plantlife, aims to promote environmental benefits such as supporting pollinators and reducing carbon emissions. This initiative has been running for eight years and has gained traction among councils looking to adopt more eco-friendly practices.

However, Dr. Elizabeth Mullineaux of the British Veterinary Association advised pet owners to exercise caution during periods of long grass growth. She recommended avoiding allowing dogs to run through tall grass and to thoroughly check their pets’ paws, ears, and fur after outdoor walks to mitigate the risks of seed contamination.

While the environmental benefits of reduced mowing are recognized, the potential health risks to pets have sparked calls for balancing conservation efforts with public safety measures. Some councils have indicated plans to review their mowing schedules and implement targeted grass cutting in high-traffic areas to address these concerns.
