Charity will now undergo the shelter's standard procedure for dogs before she is up for adoption to a new home.
The shelter procedure will bring the adult bitch up to a healthy weight, issue vet checks and watch her progress with human interaction before she is fit for adoption.
Ms Porteous said Charity will be more suited for a quiet home.
She said the SPCA have received a large amount of phone calls from people who are already keen to take in the timid dog.
"People have been ringing here offering to take her in already but once she's gone through the procedure she'll be ready to go to a new home."
Ms Porteous said Tauranga SPCA is still offering the undisclosed reward for information that will help prosecute the person responsible.
