Help Tyson! Tyson needs Osteosarcoma surgery.

Hi everyone!  It saddens me to post this.  I try to keep my personal problems away from social media.  I have a Bulldog named Tyson.  Tyson was just diagnosed with Osteosarcoma.  A debilitating bone disease.   He needs major surgery that is very costly, especially in these times.  He needs an amputation and treatment at the cost of $3600-$4500.  He needs this done asap.  I rescue dogs.  Ive had Tyson for 4 yrs now.  He's a fighter and still has a lot of life left in him.  If he doesn't have this procedure we could lose him and I simply can not afford it on my own.  Thank you for reading and for your help.
