The young dog was barely able to walk when she was found by a member of the public on Fulwood Crescent, Aspley, on December 17. The cross-breed, now named Elf, was rushed to a local vet who alerted the RSPCA.
RSPCA inspector Teresa Potter, who has launched an investigation, said it is “touch and go” if Elf will pull through.
Inspector Potter said: “This sweet little dog has been named Elf by the staff and it’s touch and go whether she’ll make it.
“She was wrapped in a towel and barely able to walk when she was rushed into the clinic by a kind-hearted passerby who spotted her abandoned in the street.
“Elf is underweight and very weak; vets believe she may have a neurological issue which could also be affecting her mobility.
“Staff are doing their best to help her survive but at the moment we just don’t know if she’ll have the strength to pull through.”
The RSPCA is appealing for anyone with information about Elf, who had no microchip or ID tag, to come forward.
Inspector Potter said: “If anyone recognises Elf, knows where she may have come from, or saw anything suspicious in Fulwood Crescent on Thursday night or Friday morning please get in touch with the RSPCA appeal line on 0300 123 8018.
“We understand that times are tough, especially over the Christmas period, but it’s never acceptable to abandon your pet in this way, particularly if they’re sick and vulnerable.

Inspector Potter added: “Animal abandonment levels have risen to almost pre-pandemic levels and we expect this winter could be even busier.
“Calls to our emergency rescue hotline passed pre-Covid levels for the first time in September showing a return to normality and, with it, rising concerns about the welfare of animals.
“Abandonments have already risen by around 20 percent this year, during recent months, compared to 2020.
“We fear a major welfare crisis with struggling charities left picking up the pieces; which is why we’ve launched our Join the Rescue campaign urging the public to support us so we can help animals in need.”
