Dogs Trust says it expects even more dogs to be given up next month, as people return to work in-person.
The charity says it has already reached capacity in its headquarters in Dublin.
As offices look set to reopen next month, so called 'pandemic pups' will be forced to readjust.
The charity has received more surrender requests in the first 8 months of this year than they did for all of 2020.
It’s appealing to owners to reach out for help in training your dog, rather than abandon your pup as life resumes to some normality.
Dogs Trust says: "Most of us humans are delighted with the easing of restrictions and the return to ‘normal’ life…..however, not everybody feels the same, especially many of our furry friends.
"Puppies and young dogs may never have known a home without people in it and even older dogs who were once used to their owners leaving to go to work, have become used to human company throughout the pandemic."
