Help Duke get brain surgery!

Hi guys, I have a sweet 3 year old Labrador with a brain tumor. Duke is a one of a kind dog and my absolute rock. The vet bills are building up and I don’t want to give up on my best friend. Any contributions would be extremely helpful. I am studying at a university so my funds are limited. This is my first time on Go Fund Me and it would be a miracle if I could save my best friends life.
