Bella is a four-year-old German Shepherd in Wooster, OH, who needs $2,000 for urgent leg surgery.

Pamela S. is one of hundreds of thousands of U.S. veterans with PTSD. But when Bella is by her side, her anxiety is at ease.

"She is my service dog," Pamela tells Waggle. "I take her everywhere. I can't be without her. She calms me down when I get triggered. She loves on me and is always sensitive to my needs."

Recently Pamela noticed Bella wasn't herself.

"One day, she refused to get on my bed or couch to lay with me," Pamela says. "I knew something was wrong. I took her to the vet. They said she ruptured her cruciate ligament, and if she doesn't have surgery, she will eventually be unable to walk. I am heartbroken. I saved up $1000, and her surgery is $4000."

All Pamela wants is for Bella to be pain-free and back by her side. Pamela is frantically trying to raise the money for Bella to have her operation at the Cleveland Road Animal Hospital.

"I sold stuff last week so that I could pay for X-rays," Pamela says. "I am on a fixed income as a disabled veteran. I recently spent my savings on health issues and relocation. I am a divorced woman struggling with all the violence in the world. It would mean the world to me to get Bella better. I can't live without her."

Pamela says in addition to Bella being her service dog, she also has quite the personality.

"She says she loves me and howls to American Idol," Pamela adds. "She knows when I am sad. She never leaves my side. Bella is my guardian angel. She is a gift from above."
