Help save my Weenie Dog.

My 10 year old Dachshund was diagnosed with IVDD last Saturday. He lost function of his back legs and lost function of his bladder. The challenge that we are having is that I can express his bladder and he cannot pee on his own. I am recovering from knee surgery that put me out of work for 3 months so funds are extremely low. I am trying to get him over this hurdle because if I can express his bladder at home he has a chance at living a longer life. He will possibly have special needs but I'm ok with that. We had a catheter put in on Tuesday and had it removed today. He got a nasty infection because of it and has a fever now. He is a fighter and I'm trying my best to help him. I dont want to give up but if I am unable to pay the vet bills I will have to put him to sleep. Anything helps. If you can donate to help me save his live I will be forever grateful. Please share. Thank you.
