Graphic footage of pet dogs mauling wild animals to death was shown to a Shepparton court on Thursday, during a Cobram man's appeal of a six-month sentence for animal cruelty.

Kaleb Kennedy, 20, is accused of training his three dogs to attack and kill deer, boar and other wild animals in rural parts of southern NSW and north-eastern Victoria.

On April 27 Kennedy was sentenced, alongside co-accused Marcus Formica, to six months in prison for a number of offences committed in a cross-border crime spree between September and November last year.

Formica is serving his prison sentence, but Kennedy appealed his term and was released on bail.
