RSPCA officers and police were called to an incident in Seven Creeks Park on Tuesday, 11 February to confront a man allegedly attempting to drown a small dog.
Witnesses raised the alarm after first seeing the middle-aged man standing in the water up to his chest with a juvenile dog which he allegedly held under water several times.
The incident occurred at the former swimming pool in Seven Creeks River.
The Euroa Gazette has seen footage of the incident in which the dog is held under water for eight seconds.
An adult female dog that appears to be the puppy's mother is seen distressed and pacing the bank.
Witnesses said police responded quickly with one officer performing CPR on the dog before rushing it to the local veterinary clinic.
The puppy was unable to recover and died shortly after.
Spokespersons for both Euroa police and RSPCA Victoria said investigations were continuing.
