I saw a program once about a dog who had lost the use of her back legs and she had learned how to shuffle round the house quite well !!
When she went out she had a little trolley to carry her back end that was attached to her with a harness,she chased her ball and played fetch too !!
Try not to worry though hopefully it will just be the one,you are lucky she is gonna make it by the sounds of it.......and by golly you could really deserve a bit of luck babe couldn't you :wink:
