In the ongoing debate about whether it’s safe to let a dog lick your face, medical experts offer contrasting views.

According to Professor Graham Roberts, a respected consultant paediatrician specializing in allergies and respiratory medicine, infants raised in households with pets have lower allergy risks compared to those in pet-free environments. He emphasizes the protective effect of early exposure to pets on allergic reactions.

In contrast, Professor John Oxford, an esteemed virology and bacteriology professor, expresses concerns about close interactions with dogs. He highlights the potential health risks associated with dogs’ habits of exploring unsanitary areas, carrying bacteria, viruses, and germs in their mouths.

On the other hand, Chris Packham, known for his work on BBC Springwatch, advocates for the benefits of dogs’ saliva for healing purposes. He points out historical practices where dogs’ licking helped prevent infections in wounded individuals during ancient battles. Packham also mentions that wolves, the ancestors of domestic dogs, have even more potent saliva with healing properties due to their natural state without medical interventions.

Packham further explains the significance of licking behaviors in wolves and dogs, emphasizing how these behaviors have evolved for survival and social communication within their packs. He sheds light on the historical reasons behind certain dog behaviors, such as consuming feces, which stem from wolf instincts aimed at reducing parasite transmission within their groups.

Overall, while opinions vary on the subject, the discussion highlights the complex relationship between humans, dogs, and their ancestral origins, offering insights into the potential health benefits and risks associated with allowing dogs to lick faces.
