A box of seven border collie cross puppies were dumped in Christchurch's Richmond Park on Valentine's Day.
The box was found by a man around 10pm.
He took the puppies home and looked after them for the night, then took them in to the SPCA the following day.
SPCA Canterbury are appealing for anyone who may know any information about how the puppies ended up in the park or who the owners might be.
An SPCA spokeswoman said unfortunately dumpings of litters happen quite often.
