Veterinary care for Bear

This is our big guy Bear.  We brought  him home 4 years ago when his previous owner no longer wanted him.  His name describes exactly what he is, a big cuddly playful bear!  On January 27th 2017 he disappeared from the farm which is unlike him, and he never came back.  On February 2nd 2017, [6.5 days later] we found him a couple miles from home in a field with a large wound in his side.  He was unable to move, but we were able to hoist this big guy into the vehicle and head to the Animal hospital in yorkton after hours.  
They did some xrays and drained his very large abcess, and we discovered somebody had shot this poor baby and left him for dead, all alone in a field for almost a week with no food or water, or shelter in the cold.  That clinic is unable to remove the bullet which is still inside, so we need to transport him to Saskatoon for surgery.  He also has a fractured shoulder.  
After all he has been through we see no other option than to make him 100% again!!  He is loved so much and has 3 other dog friends at home who want to see him come out on top.  
He already beat the odds and survived the cold, the wildlife, and the injury for a week, and we can't give up now, but Bear needs a little bit of your help.  He will need surgery, antibiotics, pain meds, fluids, a few nights in the hospital, and a long recovery afterwards which gets very pricey.  
We are willing to spend all we can on this sweet guy and I am here to ask for a bit of help!  He will be going to Saskatoon on Sunday February 5, so he needs your help as soon as possible.  Bear and his family will be forever grateful for any help they receive, and will definitely continue to pay it forward to the next in need.
