Frodo's little leg

Frodo is a 1 year old German Shepherd born with dwarfism. He has over come a few health issues and due to a medication to help him his leg grew to fast and now every time he tries to walk on it it dislocates. We have tried many things but we are at the end of the line now and he needs surgery. I am a hard working student mental health nurse and a single mother so money is very tight. I really dont want to have to put my baby to sleep so if anyone can help by giving what they can in these difficult times i would be so grateful. I will keep all updated with his progress.
Thank you
