Fundraising ideas?

Katherine
I found out this week that my puppy was born with a genetic mutation, so she doesn't have proper hip sockets. The poor thing basically walks around with dislocated hips. There's a surgery, but it's a whopping $14,000.
Now that's a lot, I know. But my puppy is my baby (since I won't have human babies right now at 20 and in university). Like seriously, she's my best friend. I'll do anything for her. So I did the obvious and created a GoFundMe and shared it. It's just most of my friends are like me and are students so not much money there, so I know I need more than that. So I'm looking to host some fundraisers for the public! Does anyone have any ideas of what has been successful for you for various reasons? Any input is much appreciated :)
