Dog ownership soared over the pandemic according to the Kennel Club, as lockdown meant people felt more able to open their home up to a new puppy.
There seems to be no letting up in the popularity of pups, as prices continue to rise as demand outstrips supply.
But now that most Covid restrictions are coming to an end, dog owners will be leaving their new pets at home more as they take advantage of rediscovered freedoms.
It might come as a shock to dogs that are used to their human friends staying in with them over lockdown, with some breeds likely to take it particularly hard.
Symptoms of the condition includude destructive behaviour, signs of stress, persistant howling or whining, and even stomach complaints.
Here are 10 of the breeds that are most susceptible to suffering from separation anxiety, according to the American Kennel Club.
Itβs also worth noting that, when choosing a puppy from the 221 breeds of dog available, these are dogs you should seek to avoid should you you be intending to leave them for more than a couple of hours a day.
