Baby is a 7-year-old Pit Bull in Kissimmee, FL, who needs $2,000 for an MRI and spinal tap.

Baby is having trouble walking and needs some immediate diagnostic tests.

Pittie Party of Central Florida saved this sweet girl, and she's been a medical mystery. Baby has been tilting her head, circling, and declining.

"She struggles to walk, wobbles, and falls," Sarah S., with the rescue group, tells Waggle. "When she shakes her head, she immediately falls and becomes somewhat paralyzed until she regains her senses. We have continued to work with the neurologist and have made accommodations to improve the quality of her life."

Baby's medical team has treated her for ear infections, vestibular disease, and neurological conditions. Now she needs an MRI and spinal tap -- both tests cost thousands of dollars. The rescue is racing to raise money for those diagnostics and a wheelchair to help her walk.

"Baby is full of spirit and determined to keep going," Sarah says. "She loves everyone she meets, and her happy smile is infectious to all. We will never give up on her, and we need your help!"
