Help Sulley Heal

Our newest doggy, Sulley, was in an automobile accident this afternoon. He lost an extensive amount of skin and tissue from the lower part of his body.  His muscles, tendons, and bones were exposed from being dragged underneath a truck almost a mile and still after surgery he still has digits in his feet and part of his legs where the bones and tendons are still exposed. We are praying that he heals quickly and hope that his wounds close without becoming more infected. He is lucky to be alive. He was rescued from the SPCA a little over a month ago and I am not prepared for the extensive vet bills that are to come now that this has happened. We are devastated, but extremely thankful that he is still alive.  Today I spent over $1200 and the vet said there is still much more work that has to be done on him and that his recovery is going to be a very long process. I am not sure that the $5500 will be enough or not. But if we raise more than he needs, any extra donations will be given to the animal shelter. But by the sound of it there's a huge chance the bills will exceed the $5500 I'm hoping for. Here is a list from his vet visit today: 
Office Visit $30
Medical Waste Disposal $4
Surgery- wound debridement extensive $700
Sterile Catheder $5
Male adapter $3.68
PRP Drops $150.50
Bandage Application $70
E-Collar $15.75
Laser Package $183.75
Unasyn $35.25
Baytril $37.88

Sulley is a 5 year old basset hound. We love him so much and want to be the very best pet family to him, especially after rescuing him from the SPCA.
