The Heartbreaking Note Left With Abandoned Dog

"We can no longer afford his treatment", said the heartbreaking note.

The RSPCA is looking for the family of a dog called Booka, who was left at a Sydney shelter with a note saying his owners couldn't afford to treat his skin condition.

Bookaboo, a four-year-old Shar Pei cross, was left at the RSPCA NSW shelter in Sydney on Wednesday night with a heartbreaking note from his owners:

His owners wrote that he had a "genetic form of mange", and they "can no longer afford" his "expensive" treatment.

"Please give him a chance, he is much loved and hard to let go," the handwritten note said.

The RSPCA has now committed to paying for Booka's treatment, and they just want to find his owners so the dog can be returned to them.

"RSPCA NSW is now searching for Booka’s family to give them the help they need. The animal welfare charity has committed to paying for all of his treatment and want him to be reunited with his family, as well as offering them the ongoing support they need," the charity said in a statement.

Around 9000 animals are surrendered to the RSPCA each year in NSW, and many are dumped in the overnight cages without explanation, but the charity told ten daily it is rare for such a heartfelt note to be left alongside a pet.

“It breaks our hearts to see loved family pets surrendered because they can’t afford vet care, and we understand that can be a really difficult decision to make,” RSPCA NSW CEO Steve Coleman said.

“You can see the pain and confusion on a surrendered animal’s face. They don’t understand what they’ve done wrong to be alone in a cage, given up by their family. And we understand that this decision can be just as painful for the family struggling to make ends meet."

The RSPCA offers assistance programs for pet owners struggling financially, as well as helping out those experiencing domestic violence, homelessness or other issues.

"We have a lot of people coming to us for help, some people are fleeing domestic violence situations and need emergency transport, others are living rough on the streets and need help with vet care and food," Coleman said.

The RSPCA said Booka's mange -- caused by skin mites -- was very common and treatable, and were hoping his family could come forward so he could return home. However, if his family can't be found, Booka will be available for adoption.
