Rotorua District Council staff have had to put down 27 dogs this week, including 11 puppies dumped at the pound over the festive season.
Animal Control supervisor Kevin Coutts said staff were upset at having to euthanase the dogs and he was annoyed at the irresponsibility of some dog owners.
He said 11 puppies, aged between 5 and 6 weeks, were left at the pound over the Christmas period and had to be put down. The puppies were cross-breeds.
Although the holiday season was generally notorious for people dumping their pets Mr Coutts said this year was particularly bad.
The dogs were held for seven days before being put down and he said several of the puppies also had to be put down because they were sick.
