The court heard Trimble-Pettitt, now of Fradley, near Lichfield, knew his dogs could escape his home and witnesses reported previous cases of them being out of his control.
In March 2023, both dogs escaped and attacked a woman and her dog at a nearby shop.
One woman stopped using a local park in January 2023 after Trimble-Pettitt warned her that his dogs were “not friendly” while they ran off their leads and ignored his commands.
Witnesses reported seeing both dogs escaping through his windows and gates on several occasions.
They were also reported to not be living in a safe environment and had no toys, blankets or dog beds.
An expert who examined the property also found the garden was “full of faeces”.
Prosecutors said the living environment meant the dogs suffered from frustration and boredom, likely contributing to them developing “extreme” aggression.
Judge Edwards said while Trimble-Pettitt did not intend for them to attack Ian Price, he displayed a “wholesale disregard” for his responsibilities as a dog owner.
