No one held out much hope for Tanner the blind, epileptic golden retriever.
Prone to seizures that left him incontinent, he had already been through two owners before winding up at the Woodland West Animal Hospital in Tulsa, Oklahoma.
Although he was only 2 years old, it seemed like euthanasia was the most humane option for the poor pup (don't worry, this story has a happy ending...)
But then... a black lab named Blair came to the rescue (hurray!)
A skittish street dog who had been found with a bullet wound, Blair was taken in by the clinic, where he met Tanner during an exercise session.
Sensing Tanner's disability, Blair began leading him around the yard by his leash. The pair made an instant connection and soon both of their conditions began to improve.
Officials at the shelter are now hoping that the pair will be adopted together so they can live happily ever after.
