Sherlock and Berlin are four and eight year-old chocolate labradors. They are two of more than 4600 labradors in the city, the most popular dog breed this year.
Labradors are by far the most popular breed, with staffordshire bull terriers in at second, and close behind in third is bichon frise.
Owners Terry Hope and Marietjie Sandford say the best thing about having labradors is "they're beautiful natured and well behaved", although they can be a handful at times.
"They have a beautiful nature, but they will eat anything that is lying around. I have to give him a lot of exercise, but otherwise, yes he's well behaved," Mrs Sandford said.
Ms Hope said one time during a dinner party she took off her shoes and put them in another room while the guests and her were eating.
"Halfway through the meal though I heard a chewing noise coming from the next room, and went to find him (Sherlock) ripping up my new expensive shoes," she said.
