The protestors are on a mission in the name of the pets they lost.
"We're not going to put up with it anymore. We don't feel it's right that veterinarians get away with things," says protest organizer, Summer Thatcher.
She says her 13 month of English mastiff, Athena bled to death after being spayed at the Quail Pointe Veterinary Hospital.
Thatcher started a Facebook page in memory of her four legged friend and says similar stories came pouring in.
"Over 100 stories have come forward by other clients as well as employees of Quail Pointe who have had animals die or get permanently injured," says Thatcher.
Now she is hoping those stories spark change. A petition drive is underway asking state lawmakers to get tough on veterinarians.
"We want the laws in Utah to change, we want veterinarians to be held to a higher standard," says Thatcher.
Quail Pointe has defended its work all along and even had a message for protesters as they arrived.
Some clients are standing by the hospital. One says she has been bringing her dog, Martha to the hospital for two years.
"Sometimes with the best of efforts and the best of skill a dog dies," says Quail Pointe client, Julie.
The protestors say it's happened too often at Quail Pointe and that's why they are speaking for the victims who can't.
"We're here for the voices of our animals and we want to see some change in Utah," says Thatcher.
