A MILDURA man who allegedly broke his six month old puppy's legs in full view of witnesses at Jaycee Park has been denied bail.

During a self-represented bail application in the Mildura Magistrates' Court yesterday, Beau Whitford denied allegations he severely injured his six-month old puppy near the park on Friday.

Police opposed Whitford's application, saying he was an unacceptable risk of failing to appear in court and of offending further.

The court heard Whitford, 27, was released on bail Wednesday last week with strict conditions, including not to consume alcohol.

Police prosecutor Al Heintze told the court Whitford was at Jaycee Park about 3.20pm on Friday when he allegedly began abusing the dog in view of witnesses, including children.

The court heard Whitford punched the dog between its eyes repeatedly and twisted its ears before two women told him to stop.

Senior Constable Heintze said Whitford abused the witnesses and threatened to choke the puppy and throw it in the nearby Murray River.

He then allegedly continued hurting his dog, holding it down by its face and suffocating it.

A Mildura Council dog catcher arrived, removing the dog from the scene, while police placed Whitford under arrest.

It's alleged wine was found in his backpack.

Sen Const Heintze said the puppy suffered a fractured back left leg, a possible broken front leg and possible internal injuries.

The puppy was taken to a Mildura veterinary hospital and Sen Const Heintze said it would require extensive surgery and possibly never recover.

He said witnesses to the incident were "traumatised" by what they saw and some had sought counselling.

Whitford told the court he had not consumed alcohol but had used synthetic cannabis the day of his arrest.

He denied allegations he abused his dog, describing them as a "load of crap".

"I stepped on my dog and that is how she became injured," Whitford said.

Magistrate Gerard Lethbridge said Whitford fell "well short of showing cause" for bail and refused his application.
