I found a young dog left in a sealed car in Dulwich Park car park yesterday. No shade. Ambient temperature 22C. After some minutes I was able to locate the owner and politely indicated to him the danger to his puppy. He was reasonable and grateful and retrieved his dog instead of continuing his fitness class.
However - I realised that I am completely ignorant as to how I could have dealt with the situation had I been unable to locate the owner. The pup was panting and squeaking and had been left with no water or open window.
I later telephone the RSPCA for information but they were unable to tell me anything except that to break into the car would render me liable to a charge of criminal damage.
Are there any guidelines as to a proper course of action?
