Dogs should be encouraged to lick people all over to improve human health, according to a leading doctor.
Dr James Kinross, Consultant Colorectal Surgeon at Imperial College London, believes dog licks can boost the diversity of microbes in human guts, making digestive systems healthier.
Kinross said: “It might be seen as gross. But there are arguments that actually what we’re really experiencing is the catastrophic loss of exposure to really important bugs.
“The majority of the world’s population live in an urban environment so we’re less likely to live with animals and in large families. This is bad for nurturing diversity in our gut microbiome and, in turn, our immune system.
“Kids in modern flats or isolated, small households don’t get to play outside or with animals as much. This will then give them a less diverse and rich microbiome.”
