How to Avoid Catching Parasites from Your Dog Safely

Dogs can pick up many parasites when outside, including fleas, worms, ticks, and fungal conditions like ringworm, which can be tough to clear. While not all parasites can pass from dogs to humans, some zoonotic diseases can infect both.

Many parasites happily infect humans if given the chance, so dog owners must protect themselves through good hygiene and parasite prevention. This article explains common transmission methods and how to reduce risks safely.

1. Be Vigilant About Preventatively Treating Your Dog

The best protection is to stop your dog catching parasites in the first place. Use veterinary-approved flea treatments and wormers as advised by your vet. Regular check-ups ensure treatments remain effective against emerging parasites, including risks like canine brucellosis, an increasing zoonotic concern in the UK.

2. Don’t Forget Your Home

Parasites like fleas can hide in carpets and soft furnishings for months. Treat your home with flea sprays or bombs every few months, especially if your dog has had fleas, to eradicate any lingering pests and protect your family’s health.

3. Clean Up Poop from the Garden Immediately

Dog faeces can harbour worms and larvae that contaminate garden soil, posing infection risks to both dogs and humans. Clean up promptly every time your dog relieves itself outdoors. Bag waste securely and dispose of it safely to break parasite life cycles.

4. Always Wash Your Hands

Hand hygiene is crucial in preventing parasite transmission. Wash your hands with hot, soapy water after cleaning up dog mess or touching your dog — especially after contact with unknown dogs. This prevents spread of worms, bacteria, and other parasites.

5. Don’t Let Your Dog Lick Your Face

Saliva from dogs can contain parasites, bacteria, and germs that cause illness. Avoid allowing your dog to lick your or your children’s faces, and wash hands whenever licked to reduce infection risk.

6. Prevent Your Dog From Scavenging Outside

Scavenging dogs risk ingesting parasites from roadkill, dead wildlife, or prey animals like rats. Control their outdoor behaviour by using a lead, walking in safe areas, or applying a muzzle if needed to discourage eating unknown items that may bring parasites indoors.

7. Keep Your Dog Clean

While regular baths don’t prevent all parasite infections, a clean coat reduces flea populations and the attractiveness of your dog to parasites. Groom your dog routinely to spot signs of fleas, mites, or skin infections early, supporting general health and comfort.

By following these practical steps, you protect both your dog and your household from parasites safely and effectively, promoting responsible pet ownership and health for all.
