Animal control officials are pleading with people to think twice about getting a pet rabbit this Christmas, due to the number of the invasive pests being found abandoned in parks and reserves. Because they breed, well, like rabbits, it doesn't take long before a population starts causing serious environmental problems. Fortunately, there's an ace team of rabbit catchers on the case. Border terrier cross Abby is the only certified rabbit detector dog in the country, and over the last eight years she's been sniffing out bunnies with her handler Gary. Louise Ternouth joined them on a hunt.
