Save Charlie's Leg

My name is Charlie.  I am about 3 years old.  I was very abused by a lot of bad people.  Shot several times with a BB gun, I still have about 6 or 7 BB's in me.  I just had surgery on my hip, but my back right leg is very weak.  I cannot put much weight on it or use it very much.  They are talking about amputating my leg. I am scared.
I was just adopted almost 3 weeks ago by the most wonderful person!  She takes such good care of me and wants to give me every chance to heal my leg so I don't lose it.
This is expensive.  The donations I am asking for would really help my "mom" pay for physical therapy, water therapy, etc. 
Whatever you can do I would be grateful.
Thanks and woof woof to you all!
