THE adoption pens at RSPCA Queensland's Animal Care Campus at Wacol are full, with more than one hundred dogs waiting in the wings.
RSPCA spokesman Michael Beatty said this time of year was always the busiest for the animal welfare organisation.
"It's a traumatic time," he said.
"Large numbers of people surrender animals because they haven't planned for kennels or someone to look after their pets if they're going on holidays.
"When you combine this with the fact that we already have large numbers of animals looking for homes you can begin to understand the problem."
Mr Beatty said it was a misconception that the RSPCA discouraged people from buying pets at Christmas.
"We actually encourage the responsible buying of pets," he said.
"The Christmas holiday period is the ideal time for the family to bond with their new pet and start training sessions.
"However we do say that you should never give a pet as a surprise gift and the person who will be looking after the pet must be involved in its selection.
"For a family this obviously means the whole family should be involved."
Mr Beatty said the RSPCA had special gift vouchers which meant the person receiving the voucher could then choose a pet at their leisure.
"This puts an end to any suggestion of impulse buying," he said.
RSPCA Qld is also reminding the community of its Home Alone program.
The program allows people to register the contact details of the people who may be caring for their pets while they're away.
"In the past we've had pets being reported as abandoned when in fact there was someone coming to feed and walk them every day," Mr Beatty said.
"This way we can simply ring the people listed and check that everything is okay.
"While we don't recommend pets being left home alone for long periods, it's a perfect solution for people taking short breaks."
