How to convince my mom to get a Bulldog?

We are thinking of getting another dog because we had to put our beloved dog Maggie (a Shetland Sheepdog) down about 3 weeks ago. She was sooo pretty, and sweet. I was thinking of getting a bulldog, but my mom says "UGH THEY'RE SO UGLY! WE ARE NOT GETTING ONE!" lol. So any way for me to convince her?
