What is it about animals? As the bad news about the coronavirus continues, “send me dogs and cats” has become a regular cry on social media, an easy-to-grasp shorthand for “I feel terrible, cheer me up”. The response is always the same: a torrent of pictures of animals doing daft things – but somehow it has a magical, calming effect.

The therapeutic value of our relationship with our pets, particularly dogs, is increasingly recognised by researchers. Cats can be wonderful too – but dogs have been domesticated by humans for much longer, and, as even the most devoted cat lover will admit, dogs are far easier to train for companionship. Most cats, as we know, are admirable for entirely different reasons. Marion Janner, a mental health campaigner and all-round animal lover, says that dogs teach us a whole range of lessons. “Dogs love us unconditionally. They’re the ultimate in equal opportunities – entirely indifferent to race, gender, star sign, CV, clothes size or ability to throw cool moves on the dance floor. The simplicity and depth of this love is a continuous joy, along with the health benefits of daily walks and the social delights of chats with other dog walkers. They teach kids to be responsible, altruistic and compassionate and, valuably but sadly, how to cope when someone you love dies.”
