Dudley’s CCL repair

Our 6 year old Lab Dudley, ruptured his CCL  last month. 
As all my friends know, because of our crappy last few years with all of Dave’s injuries and surgeries, we could only afford the least expensive surgical repair and we had it done on November 29th. 
Dudley was healing really well but starting Sat am, he was limping worse and eventually no longer putting weight on the leg at all. 
Our vet confirmed today that the surgery failed. 
It goes against my nature to ask for help but this is our only option to not have to put Dudley down. 
I can’t  watch him suffer in pain and not be able to walk and play. 
Please consider donating so Dudley can have a more stable surgical repair. 
Thank you all so much!
