"She is just beautiful. She has bounced back and realised there is quite a lot of love around."
Mrs Johnson said what the dog had been through was "just horrendous". It was likely the puppy hadn't been off the chain for four to five weeks, and was chained up most of her life. They think she is about 3 or 4 months old.
The chain hadn't been made bigger to accommodate the growing puppy, so had embedded itself in the dog's neck. It was about 1cm away from the jugular vein, which meant the dog was about a week away from dying.
The dog has been at the centre for just over a week and Mrs Johnson said staff and volunteers were spending plenty of time with her, teaching her basic commands and how to play.
"What she wasn't used to was playing."
Mrs Johnson said they were talking to a man who was interested in taking her to live at his farm. "I don't think we will have any problem rehoming her. She just needs some TLC."
The SPCA is investigating who was responsible for leaving Anzac chained up.
