Surgery for Snickers

Our sweet baby snickers was hit by a car. She made her way home but is severely injured and the vet has said she may need to have her leg amputated due to the severity of the break. We have two boys ages 8 and 10 who love her so much. She is apart of our family. It’s a very expensive surgery and we are lacking on the funds as of right now. Any help would be appreciated.
Thank you to anyone who takes the time to read this.
