Help Darko the Husky walk again

I am Darkos Mom on 9/24/20 his Dad was taking him for a walk and Darko twisted him up in the leash and got away from him. They were on the sidewalk and Darko darted into the street. There was an 18 wheeler coming and he couldn't get out of the way fast enough and his right front leg got run over. Needless to say we are devastated as Darko will only be 6 months old on 10/8. His leg is fractured and he has to be splinted for 4 to 6 months. He has to go every week for a splint change and that will be $70.00 a week. Dad doesnt work due to PTSD, and I work 6 days a week most weeks. But this is a little more than I can pay for. Please help us help Darko be able to play and run again. Anything over what we need for his care will be donated to Purrfect Purrbaby Rescue who so kindly helped us with his initial care. I greatly any and all help we can get... Thank you so much.
