Should I Let My Dog Kiss the Kids? Risks & Benefits Explained

Many parents wonder whether it is safe and appropriate to let their dogs kiss or lick their children, especially young kids. While a dog’s affectionate lick may seem endearing, reputable breeders and vets urge caution due to the potential health risks and behavioural implications.

Recent research has softened the once harsh view that dog saliva is a hotbed of harmful bacteria, and some findings even hint at certain benefits. However, the balance of evidence and expert opinion suggests that parents should manage these interactions carefully and keep hygiene in mind.

1. Understanding Bacteria in Dog Saliva and Risks for Children

Quick Answer: Dog saliva can contain bacteria like Pasteurella, Salmonella, and E. coli which pose infection risks, especially to babies and immune-suppressed children.

Dogs frequently ingest and carry bacteria picked up from their environment, some of which can be zoonotic, meaning transmissible to humans. Pasteurella is common in dog mouths and can cause infections if it enters broken skin or mucous membranes. Additionally, intestinal bacteria such as Salmonella, Clostridia, E. coli, and Campylobacter may be present in dog faeces and can contaminate their mouths during grooming.

While not every dog carries harmful levels of bacteria, and transmission to children through licking a face is less common than bites or scratches, the risk is non-negligible. The youngest children, especially under 1-year-old infants, and those with weakened immunity are the most vulnerable to infections and should be protected from such contact.

2. Parasites That Can Be Transmitted Through Dog Saliva

Internal parasites may also be transmitted through a dog's saliva if they have recently cleaned their rear end. Parasites like Giardia and Cryptosporidium are notable exceptions that can infect humans directly from parasite eggs in the dog’s mouth. These infections can be serious, causing gastrointestinal issues, skin conditions, even vision and neurological problems in extreme cases.

Regular deworming and veterinary parasite prevention protocols are crucial to minimise these risks in any household with children. Teaching children to avoid facial contact and ensuring thorough handwashing after contact with pets can reduce parasite transmission possibilities.

3. Possible Benefits of Dog Saliva

Dog saliva contains compounds such as histatins and Nerve Growth Factor which may promote healing of minor wounds and reduce bacterial infection risk on open cuts. The production of nitric oxide on saliva contact has anti-bacterial effects. Ancient beliefs, such as those held by Egyptians, considered dog saliva as a natural healing agent.

More recent scientific studies have found some associations between early life exposure to dogs and reduced development of asthma and allergies, possibly through immune system stimulation from bacterial exposure. However, these benefits do not outweigh the potential health risks of dog-to-child saliva contact on the face.

4. Behavioural and Safety Considerations

Beyond health, allowing dogs to lick children’s faces may unintentionally reinforce dominance behaviours in dogs – they might perceive such interactions as a status signal. This dynamic can increase the risk of aggressive behaviours or bites.

Supervision and teaching both children and dogs proper interaction etiquette is paramount. Children should be taught not to encourage licking on the face, and dogs should be trained to show affection in safer ways, such as licking hands. Avoiding face licking helps maintain a respectful and safe relationship within the family.

5. Keeping Things Hygienic and Safe

Regular veterinary checks, including dental health assessments and parasite control, are essential to keep your dog as healthy as possible. Prompt and proper wound care if a dog does lick any cut or sore is also vital. Teaching good hygiene habits not only protects children but also helps prevent spreading germs within the household.

After any licking, particularly if directed at children’s faces or hands, gently cleaning the area is advised. Washing hands frequently and regularly cleaning pet beds, toys, and living areas helps reduce the risk of infections.

6. What Does the UK Vet Community Say in 2025?

According to current veterinary guidance in the UK, it is generally recommended to avoid allowing dogs to lick a child’s face, particularly babies under 1 year and children with immune concerns. While the risks are not extremely high, they are sufficiently significant to warrant precaution.

Experts suggest that families can safely enjoy close affection by encouraging dogs to lick other body areas, such as hands or feet, but not the face. This approach balances the dog's natural behaviour and the child’s health safety effectively.

7. Making the Decision: Balancing Love & Safety

Ultimately, whether to allow your dog to kiss your children is a decision each family must make considering their dog’s health, behaviour, and the children’s vulnerability. Responsible dog ownership means knowing your pet well, practising good hygiene, and teaching children how to interact safely with their canine companion.

By prioritising these practices, you can enjoy the benefits of your dog’s love and affection safely, without unnecessary health risks.

Conclusion

Dog kisses on children's faces carry both potential benefits and significant health risks, especially from bacteria and parasites that dogs may carry. The safest approach, recommended by UK vets and pet experts in 2025, is to avoid allowing dogs to lick children’s faces, particularly those under one year old or with compromised immune systems. Instead, encourage other forms of dog affection, maintain regular veterinary care, and teach children proper hygiene and dog handling for a happy, safe relationship between your kids and dog.

For those looking to add a furry friend to the family, finding a puppy from a reputable breeder ensures a healthy start, making safe interactions easier and more enjoyable for everyone.
