Five-week-old puppy found in wheelie-bin outside a Wingfield property HEARTLESS: The 900 gram female puppy that was found dumped in a bin, is under constant vet care. THE next few days could be the most important of this puppy's life. The five-week-old dog will spend Australia Day under the around-the-clock watch of veterinarians after she was found dumped in a wheelie-bin outside a Wingfield property last night. Vets also suspect she had been physically abused before she was dumped. The crossbreed puppy was rescued by the owner of the property, who heard rustling from inside the wheelie bin when he came home about 9pm. It is not known how long she had been there for, but inspectors believe she was likely dumped at the Grand Junction Rd property on the same day. Kerriann Campbell, executive manager of Animal Operations for RSPCA South Australia, said it was an "inexcusable act." "No animal deserves to be treated in such a way," said Ms Campbell. The puppy was emaciated ... there are definite signs of neglect and veterinarians are investigating the possibility of the puppy having suffered physical harm prior to being dumped. The man who found the puppy gave her some food and water before taking her to an emergency vet clinic, where she remains in a critical condition. She is being treated for emaciation, worms, fleas and other suspected internal injuries. RSPCA SA Inspector Pieter Mur, who is leading the investigation to find the puppy's owners, said she would not have survived much longer in the bin. "She was already critical, so she wouldn't have survived the night," Mr Mur said. RSPCA CEO Tim Vasudeva said there were many alternatives for dealing with unwanted puppies. "It's just a total lack of compassion," Mr Vasudeva said. You can surrender them to the RSPCA or other welfare groups. The RSPCA is appealing for information from anyone who may have seen someone acting suspiciously in the area, particularly people driving along Grand Junction Rd. Anyone who believes they may have information is urged to contact RSPCA's 24-hour cruelty line on 1300 477 722. The RSPCA said the dog will be put up for adoption once it makes a full recovery.
