Yes, the police often express irritation, even anger, that the SPCA has left a suffering dog where it is, even in conditions that are a clear offence under the PCA Act and that they are often forced to enforce the law that the SPCA is supposted to enforce. Police expressing gratitude is not unusual.
Nor is it unusual for police to go back, off duty and out of uniform, and remove the dog and get it to a rescue group or rehome it.
Nor is it unual for teachers, nurses, doctors, lawyers, crown counsel, social workers and other professionals to have removed a suffering dog that the SPCA has said is "fine".
This is going to go on until the SPCA starts seizing single yard dogs the way it seizes media-attracting and sellable pure-bred puppymill dogs like these it seized....
