Penny is a 8-year-old Chihuahua Basenji mix in San Diego, CA, who needs $2,000 for urgent surgery.

It all started when Penny ran over to pick up her favorite toy. She stopped, cried, and her human family panicked.

"She was no longer able to use her back right leg," Christina D., one of Penny's family members, tells Waggle.

It turned out poor Penny tore her ACL ligament in her knee. The expensive surgery needed to fix it is something Christina and her family can't afford.

Their expenses are higher than their income, and their rent just went up. They spent more than $1300 on Penny's diagnostic tests, and the operation is another $4500. It's a heartbreaking situation.

"When my family adopted Penny from the shelter, I thought it was a sign for us to take her home -- her kennel card said her name was Penny -- the same name of the black Lab we had we I was a kid," Christina says. "We now cannot imagine our lives without her. She's loving, protective, and feisty."

Please help Penny get back on her feet again!
