LONDON, ENGLAND - DECEMBER 28: Rose, a three-year-old Rottweiler puppy, who is looking for a new home, sits for a portrait at Battersea Dogs and Cat's Home on December 28, 2016 in London, England. Rose was brought in to Battersea after her owners, who bought her off the internet, found out they were not allowed to keep pets in their house. According to the charity, "She's a bundle of energy and love. She's full of beans and needs new owners who can help teach her the ways of the world. She's a great puppy, looking for a home with people with guarding breed experience and can help her mature in to the lovely lady we know she can be". Battersea Dog's and Cats Home was founded 150 years ago and has rescued, reunited and rehomed over three million dogs and cats. The average stay for a dog is just 28 days although some stay much longer. Around 550 dogs and 200 cats are provided refuge by Battersea at any given time. (Photo by Dan Kitwood/Getty Images)
