With as many as 13 greyhounds traipsing around their family home at any given time, Peter and Janet Flann pace their days, packed with vet visits and daily walks to the park.

But the dogs are often just temporary visitors as the retired couple rehabilitate the dogs for new lives outside the race track.

As the founders of not-for-profit organisation Greyhound Rescue, the couple have helped find new homes for more than a thousand greyhounds rescued from pounds, trainers, and breeders over the past decade.

But following the NSW government's announcement of a ban on greyhound racing last week, the organisation has detected a jump in the need to relocate unwanted dogs.
