Almost a quarter of owners fear they will not be able to provide a suitable home for their dog post-lockdown and 17 percent have considered rehoming, the survey found.
The Kennel Club warned the UK was facing a looming “welfare crisis for pandemic pups” unless more workplaces become dog friendly.
Bill Lambert from the The Kennel Club said: “This new research worryingly shows that if dogs can’t go to places with their owners, and fit their lifestyle post-pandemic, some will be left home alone for too long, or even sadly rehomed or abandoned.
“These consequences could be quite devastating for the nation’s dogs, who frankly don’t deserve to be left behind after being a lifeline for so many during lockdown.”
As many as 21 percent of owners admit leaving their dog at home alone for long periods of time, according to the research.

And 14 percent said they have left their pet in the car while shopping, the study found.
The Dog’s Trust charity warned between August 2020 and January 2021 there was a 41 percent increase in traffic to its Giving Up Your Dog webpage.
While Battersea Dogs & Cats Home has predicted it will see almost 27 percent more dogs abandoned in the next five years.
Mr Lambert urged the hospitality, business and workplace circles to make places more dog friendly for people across the UK.
He added: “Hospitality, businesses and workplaces can play a role in combatting the looming welfare crisis faced by this pandemic pup generation by being open for dogs; helping owners to introduce or re-introduce their pet to ‘normal’, without leaving them behind.”
