The Lurcher is being looked after at the Dogs Trust after a member of the public spotted her just before 11pm in a muddy Gildersome field on Sunday.
Rain – who was about three-quarters of the weight she should have been – was taken to a York Road rehoming centre by the dog warden on Monday, where she was immediately seen by the vet.
Amanda Sands, rehoming centre manager at Dogs Trust Leeds, said: “She was in such a state when she was brought to us, very frightened and timid which is no surprise given she obviously hasn’t been looked after for some time.
“Her ribs are clearly visible so there has been severe neglect.
“She is significantly underweight, weighing only about three-quarters of what she should. Rain is also quite weak so she is having four meals a day to help her gain weight and strength.”
The team believe Rain is only around a year old and she has already had at least one litter of puppies.
She was found without a collar or tag and is not microchipped.
Amanda said: “She is such a young dog and at her age should be full of bounce and confidence so it’s really sad to see her this way, but we’re hoping over the next few days her true personality will start to shine through.
“She is now getting lots of care and attention from the staff, she has a big, warm, soft bed to sleep in and is being taken on nice, gentle walks – everything all dogs should have the chance to enjoy.
“In a few days she’ll be ready to head off to a new home where she will get all the love and kindness she deserves, so we’re now just waiting for her special someone to come to visit.”
