Shocking footage captures the moment a woman rages at a military veteran after he brought his PTSD dog inside restaurant.

Workers and diners queued up to defend the serviceman who remained silent during the unpleasant verbal onslaught.

Holding the lead, the veteran stands near his dog, which appears to be a Great Dane mix with an official military coat wrapped around its body. The animals help victims of serious injury or accident feel safe during potentially difficult social situations.

When the screaming woman claims the veteran is not allowed to bring his dog inside, one waitress is heard shouting: 'He's allowed because he fought for our country.'

The aggressive diner then responds erratically, claiming her husband's father was also a serviceman who died abroad, and continued screaming: 'It's nasty to me, it's f******* disgusting,' before calling various diners w***** and b*****.

Standing alongside a seemingly embarrassed male companion, the woman continues her tirade as the veteran tries to calm her down.

'There should be a separate section for the f****** animals,' the woman continues to rant.

She then can be seen threatening staff, demanding: 'Who's gonna shut me up? Are you gonna make me? [sic]' pointing at workers.

The staff try to encourage the woman to leave, telling her she's welcome to go eat somewhere else but she continues to rant.

After swearing and threatening more diners, the woman leaves the restauraunt only to walk back in and shout: 'It's my opinion, none of y'all are gonna change it. It's disgusting, it's gross!'

A woman off camera attempting to explain to the woman it's legal to allow dogs inside is again shouted down.

The video immediately went viral with online users criticising her abusive tirade.

'What an ignorant woman. My dog jumps on my bed and walks over my pillow etc and I am still alive. Unless you are allergic then STFU. My dog makes me stronger and someone like her in my life would just make me weaker. Which would I choose?' one said.

Under law by the Americans with Disabilities Act (ADA), a service animal is defined as a dog that has been individually trained to do work or perform tasks for an individual with a disability.

'The task(s) performed by the dog must be directly related to the person's disability,' the government website added.
