How to Treat Yard for Dog Worms & Prevent Reinfection

Intestinal worms can infest many animals including dogs, cats, and wildlife. In the UK, wild animals such as rodents, foxes, rabbits, and hedgehogs commonly carry worms, which can contaminate the environment.

Veterinary-approved worming treatments are essential for eradicating worms in your dog and protecting their health. However, these treatments target worms your dog currently has and do not provide ongoing protection against new infections in the days following treatment.

This means your dog could potentially pick up worms again soon after treatment. Worming schedules are designed to maintain your dog’s health by preventing worm populations from building up to harmful levels, not as a continuous shield against reinfection.

Completely preventing your dog from picking up worms is impossible, as worm eggs and larvae are microscopic and thrive in many environments. Yet, alongside regular worming, there are practical steps to reduce reinfection risk.

Worm All Pets Simultaneously

If you have multiple pets susceptible to worms, including other dogs or small animals, it is crucial to worm all at the same time. Treating one animal alone can lead to reinfection from untreated animals within your household within days.

Promptly Clean Up Dog Faeces

Dog faeces are a major source of worm egg and larvae spread. Leaving faeces on your lawn or garden allows worm eggs to infect the soil, increasing infection risk for all pets.

Always pick up after your dog promptly and thoroughly clean your outdoor area, especially after worming treatments, to break the worm life cycle.

Disinfecting Your Garden

Worm eggs and larvae can remain in the soil even after faeces removal. To reduce environmental contamination, consider using lawn disinfectants designed to be safe for grass but reduce parasites.

You may also explore natural options like introducing beneficial nematodes, microscopic organisms that prey on worm larvae in the soil, or applying food-grade diatomaceous earth as a non-toxic abrasive against larvae.

Avoid High-Risk Public Areas

Walking your dog in areas heavily frequented by other dogs, such as dog parks or popular public lands, increases exposure to worm contamination if owners do not clean up after their pets.

Limit visits to such areas or opt for cleaner, less crowded spaces to reduce reinfection chances.

Clean and Disinfect Toys and Feeding Areas

Wash your dog’s toys, food and water bowls, and outdoor play equipment with hot water or disinfectant during worming treatment periods. Avoid sharing toys or communal bowls with other dogs not living in your home to limit infection spread.

Wash Bedding and Soft Furnishings

Regularly hot wash your dog’s bedding, blankets, and any soft furniture they frequently use. Sanitize or disinfect hard surfaces to reduce environmental worm eggs lingering in your home.

Prevent Hunting and Scavenging Behaviour

Dogs that hunt rodents, scavenge roadkill, or roll in wildlife droppings have a significantly higher risk of picking up worms. Use muzzles or keep your dog on a lead in uncontrolled areas to prevent these behaviours.

Provide Only Safe, Cooked Food

Avoid feeding your dog raw or improperly cooked meat unless strictly following the BARF feeding protocol with rigorous safety standards. Raw meat can harbour worm eggs and larvae.

Clean Your Dog After Walks

Wiping your dog’s feet and coat with antibacterial wipes or a damp cloth after walks reduces the chance of bringing worm eggs indoors and lowers reinfection risk.

By combining regular veterinary worming and these environmental management steps, you create a safer, cleaner space for your dog and significantly reduce worm reinfection risks.
