12-week-old bulldog can't fit in her old booster seat

A 12-week-old English bulldog named Bertha tries in vain to fit into her old car sear, which she could happily fit in the week before.

However, Bertha has been growing at an incredibly fast rate, and doesn't quite understand what is happening.

"She had outgrown the chair and couldn't get it in her head," said the owner. "She was trying over and over but she couldn't fit in it."
