Owning a dog is a source of great joy for many, offering companionship, increased physical activity, and improved mental wellbeing. However, concerns about health and hygiene risks associated with dog ownership are common and understandable. This article explores whether dogs pose a health or hygiene risk, the veterinary and medical consensus in the UK as of 2025, and practical advice to minimise potential risks.
While dogs can carry germs and occasionally transmit infections, the risk of serious zoonotic diseases (those transmitted from animals to humans) is very low in the UK. Common zoonoses include infections like Campylobacter, roundworms, hookworms, and certain tapeworms. Routine veterinary care with regular vaccinations, deworming, and flea control significantly reduces these risks.
Dog bites and scratches can cause injury and sometimes infections. Most bites happen due to misunderstanding a dog's behaviour or in situations that provoke fear or pain. Learning to read dog body language, training dogs properly, and avoiding unknown or aggressive dogs can prevent incidents. If bitten or scratched, prompt wound cleaning and medical attention are essential to prevent infection.
Dogs can bring dirt, bacteria, and parasites into the home environment, but maintaining good hygiene reduces these risks. Regular grooming, cleaning dog bedding, and washing hands after handling your pet or cleaning up waste are important routines. Immediate and thorough cleaning after dog accidents and faeces, along with the use of protective gloves, helps keep your home hygienic.
Some individuals are allergic to pet dander, saliva, or urine, which may trigger asthma or allergic reactions. Being allergic to one dog breed does not necessarily mean all breeds will cause reactions. Those with compromised immune systems, young children, or elderly people should take extra care and consult healthcare professionals regarding dog ownership. For many, allergy management strategies and selecting hypoallergenic breeds may help.
Experts agree that responsible dog ownership — involving up-to-date vaccinations, regular parasite control, and good hygiene — makes dog ownership safe for most people. The benefits of having a dog generally outweigh the manageable risks.
Healthcare settings adopt strict protocols for dog visitors, ensuring no increased infection risk. At a population level, there’s no evidence of widespread health problems caused by dog ownership where responsible care is standard.
Owning a dog in the UK in 2025 is not a significant health or hygiene risk when best practices are followed. Although dogs can carry certain pathogens, responsible pet ownership and hygiene dramatically reduce any risk to human health. As always, special consideration is needed for vulnerable individuals. Beyond health concerns, dogs enhance quality of life, offering companionship and encouraging physical activity.
