Eric and Susan Hermann's dogs Sasha and Mocha spark fight amongst billionaires in Park City, Utah, as neighbors are split over future of the pups

Locals in Park City have been left split after a property dispute that saw one angered resident file a lawsuit against his neighbors dogs. 

Matthew Prince, co-founder of tech firm Cloudflare, had originally been engaged in a suit about a rock wall over a property line with Eric and Susan Hermann. Lawyers for the billionaire then filed a suit against the Hermanns two Bernese Mountain dogs, Sasha and Mocha, claiming the two are 'vicious and aggressive.'

Prince, who's worth $3.4 billion, has also claimed that the two dogs have 'aggressively approached, chased and harassed' him and his family. 

Prince told the Wall Street Journal: 'I get that we’re rich a**holes, but at some level I’m also a father and I have to protect my daughter.' 

The Hermanns have denied the allegations saying the dogs are 'well-behaved, polite and nonaggressive'. They also say the suits are in retaliation after they appealed the city's approval of his plans to build a mansion overlooking the historic center of the town.  

While the two go after each other with litigation, locals have been left split in their support of the dogs.

Prince filed suit against the couple over the behavior of their Bernese Mountain dogs, calling them 'menacing.' The owners said they had never received such a complaint prior to the appeal, and claim they are now being harassed by the billionaire couple

According to the lawsuit, the 100-pound-plus dogs have also been barking loudly and relieving themselves on Prince's property. 

Hermann told the Wall Street Journal: 'If such a thing might ever occur, we would of course pick up the dog poo', adding that he had never seen his dogs urinate there.

He also told the outlet that he believes the suit against his beloved canines amounts to harassment. 

Price said the two dogs had menaced his 82-year-old mom and 'barked, snarled and charged' at his toddler. 

The Hermanns said he never asked them to leash their dogs before the filing, and that 'the dogs have had no interaction with the Princes.'

Since the fight erupted about the two pooches, locals have came out in support of Sasha and Mocha, making 'Free Sasha & Mocha' stickers. 

The outlet said  the stickers have begun appearing on signs, fence posts and car bumpers around the city. 

Blaire Dernach, a local bartender, described the dogs as being 'big, fluffy and beautiful'.

While neighbor Teri Toelcke, 79, said she had concerns about the dogs, saying: 'They don’t want you near their people.'

Prince claims the rock wall (circled) crosses the property line between the lot he bought a few weeks ago and the lot next door. The Hermanns say he purposely bought the lot a few weeks ago out of spite

The Cloudflare kingpin - who's worth a reported $3.4billlion - moved to Park City from the Bay Area after the pandemic

The rock wall that started it all belongs to Eric, 71, and Susan, 68, and makes up part of their $11.5million mansion. 

They claim a rock wall coming from their home crosses the property line into the vacant lot that Prince bought last March. 

The pair have emerged as two of Prince's fiercest adversaries in an ongoing property fight, filing an appeal earlier this year after Prince received approval. They argue his proposal violates zoning laws - a declaration eight others in the neighborhood, including some friends, have rallied behind. 

They also say he purposely bought a second patch of land after the first suit so he could file a second. 

In February, the Park City Planning Commission gave preliminary approval to the pair's plans to raze two houses on the hill where the Hermanns live to make way for their new home, under the pretense they be subject to a raft of conditions and a design review. 

The conditions include that the home be limited to under 7,500 square feet, as well as restrictions on lighting to limit the impact on neighbors. 

The commission approved the proposed property by a narrow vote of 4-3, The Hermanns, however, were not convinced - filing an appeal March 1 seeking to reverse approval of the Prince's home plans.

The couple say the project isn't in line with local development rules, and the planning commission failed to provide ample consideration for the impacts the home will have, by not properly enforcing the city's development code.

The wall belongs to  the 71-year-old and 68-year-old Hermanns, who also own this $11.5million mansion. The pair have thus emerged as two of Prince's fiercest adversaries in an ongoing property fight

Price wed his wife in 2017, with the pair since purchasing local publication the Park Record. The neighborhood appeal is set for review by Park City's three member appeal panel on April 30, after which the matter will be settled

Residents have complained the plans for the house are too large, and violate codes for maximum footprint of 3,500 square feet. 

It would also have an interior height of 53.5 feet, which is 18.5 feet more than what officials believe is allowed, according to a commission report. 

The Hermanns wrote in a summary: 'It will loom over Old Town, glow at night, and reflect the morning sun onto the rest of Old Town.'

The Princes argued that the city have miscalculated claiming that only 3,475 square feet would be used as the aboveground 'building footprint'.

Total living space would account to 7,351 feet and the interior would be complaint at 35 feet. 

Neighbor Pat Sweeney said: 'All he’s doing is replacing a house with a new house.'

Prince said that the relationship between himself and the Hermanns started out in 2022 when he and his wife Tatiana went to their house to 'talk about their plans'.

After learning the Hermanns owned an undeveloped lot next to him, Prince inquired and offered to pay one and a half times market price. 

The Hermanns declined and acknowledged their Berneses' behavior in a text, saying: 'Next time we will manage your arrival so that the dogs are snugly and not scary.'

Hermann told the journal that was a joke, while Prince said they had been aggressive. 

The neighborhood appeal is set for review by Park City's three member appeal panel on April 30, after which the matter will be settled one way or another.
