Toph, 1 Yr old Puppy needs knee surgery

Toph,  Our sweet little(big) girl.   She is just a puppy.  She is ONE year old.  She needs a knee surgery.  She is a very bouncy little girl.   This injury has not taken her spirit away.   Although every bounce sets her back.  She loves pouncing on her brothers when we take her to the beach.  She loves to cuddle by taking up the whole bed.  She loves running through the clover patches in the redwoods back in california.  She loves chewing on hooves.  The stinkier the better.  There is no mud puddle that can stop her.  The dirtier she gets the happier she is.  It is hard to keep an 85lbs puppy from moving.   She is a rescue.  We love her very much.  The thought of her staying in pain is killing us.  We however cannot afford this surgery.   We would greatly appreciate any help.  Thank you everyone who has helped out.   We know times are hard for everyone.   We appreciate the kindness you have shown to us and our little girl Toph.
