The most adorable underbite ever

My dog Bella in my (biased) opinion has the cutest underbite ever! I wish we knew what mixture of breeds she is, as an underbite is usually seen in certain ones. The local shelter we adopted her from said she is a poodle mix, and we have a feeling she might have some shih tzu or westie. Either way, we love getting to see this adorable little face every day!
