An intoxicated cafe owner, who tried to take a dog for a walk in the middle of the night, assaulted two people and pulled out a blade when he was told no.
Colton Clark had given the dog to with a friend, but then said he wanted to keep it for himself. He turned up at a property in Twenty Acres Road, Brentry, demanding to be able to take the dog out.
A violent tussle ensued in which he picked up a blade and assaulted a man and two women.
The 23-year-old, of Elmfield Road in Westbury-on-Trym, pleaded guilty to assault occasioning actual bodily harm, affray, threatening with a knife and two common assaults on February 29.
Judge Julian Lambert jailed him for two years.
The judge told Clark: "You are prone to offending with a temper.
"Its drink and drugs behind this.
"You took leave of your senses."
James Le Grys, prosecuting, said in July last year Clark bought Brook Muckley a dog.
But after he then said he wanted to keep it himself, the pet remained with Brook and her mum Kerrie.
When an apparently drunken Clark turned up at their home on February 29, asking to take the pet for a walk, trouble flared.
Mr Le Grys told Bristol Crown Court Clark grabbed a knife and headbutted both women.
When neighbour Matthew Brunt intervened outside the property Clark squeezed his testicles as they struggled, and was ultimately restrained before police arrived.
Ramin Pakrooh, defending via Skype due to coronavirus lockdown, said the women had helped his client in the past and he was very remorseful for what happened.
He said his client had a traumatic background and the incident amounted to an escalation in offences.
Mr Pakrooh told the court his client had begun to run a cafe last year which was initially running at a loss before showing a profit before lockdown.
In November last year Bristol Live reported how, as owner of Cafe on the Avenue in Filton, Clark was set to offer free meals to rough sleepers twice a month.
Clark hoped the business would become more than just a place to eat and planned to help those in need.
He explained he was able to open his dream business, serving breakfasts, salads and sandwiches, after being awarded compensation from an accident.
He told Bristol Live: "I grew up in Southmead and was surrounded by a lot of crime.
"When I got this money I wanted to use it on something worthwhile."
