He has been living at the RSPCA for "20 months too long" - and is desperately searching for somebody to take him home.
Greyson, a smooth-haired dachshund, has spent his entire life at the RSPCA's Newport Animal Centre after his pregnant mum was taken into their care.
The one-year-old has been described as a popular dog who "really enjoys playing with squeaky toys and having many cuddles from his carer".
