An eight-week-old puppy has been bashed, burned and left for dead in an Altona Meadows park.

A passer-by found the puppy in Truganina Park at about 7pm on Wednesday night, taking it to Animal Accident and Emergency in Point Cook.

The puppy was still alive but had significant internal injuries and veterinarians had to make the heartbreaking decision to put her down yesterday morning.

The RSPCA believes the puppy was bashed and burnt several days before being dumped in the park.

The organisation has made a public appeal for information to help identify those responsible.

RSPCA senior inspector Daniel Bode said the abuse was inexcusable. 

‘Clearly it is the intention of the offender or offenders to not only cause the death of this puppy, but to inflict pain and suffering as well,’ he said.
