Help Jelly Bean with her injuries

This past Saturday Jellybean was living his best life in his home and he was attacked by another dog. The owner of the pitbull said that the dog was friendly with all animals and children. The owner let the dog in the trailer, cornered and viciously attacked Jellybean in front of two children. Jellybean has many injuries, a fractured jaw being one, a laceration to the top of his head, the inside of his mouth is tore requiring many stitches, tissue damage and he is on a feeding tube as there was an abscess firming from the dog bite that was blocking his airway, thus, needing surgery and requiring many expensive medical treatments, and follow up vet visits. The owner of the dog has vanished. Both the police and animal control have been notified. Jenny is a single mom with a little boy. Jellybean is a family member they love dearly and trying to save his life has put them in a financial bind. Jellybean is a very affectionate, loving, goofy boy that loves hugs. If anyone could help it would be very much appreciated. On behalf of Jellybean, Jenny and Rez, thank you kindly.
