Meet Belle, whose doctor diagnosed her with a birth defect that makes her look permanently surprised.

The adorable mix of doberman and cattlehound was born with the muscles in her head stretched back, leaving her looking wide-eyed at all times.

Lieschen O’Connor adopted Belle in 2017 from Lawrence Humane Society, an organization that provides care for homeless and abused animals.

Belle’s condition doesn’t cause her any pain but her 38-year-old mom regularly needs to apply eye drops as they often get dry.

The dog’s unique look has won her over 160,000 followers on TikTok.

“Her expressions make my heart swell,” said one fan. Another called her the cutest dog on TikTok. “I love her so much”.
