Saving Lucky my service animal

Lucky is my 7 yr old service animal for Panic Anixity and PTSD.  On Sunday evening we went to go out to eat and in the parking lot of Texas Roadhouse he stepped in antifreeze.  He started vomiting Monday and I rushed him to the Vet in West Ashley .He had been admitted. He has IV, liver medicines, had ultrasound today.  Tons of blood work. His liver enzymes level were at 1808 last night they have dropped to 1500 which is still dangerously high.  We are here again tonight.  Since he is my service animal and beloved companion. He is refusing to leave my side. I had multiple attacks last night while he was in the back being treated.  They finally have set us up in private room so we can be together for his wellbeing.  His vet bills are at 1300 as this morning. Now the ultrasound cost and another nightstay and maybe tomorrow night too depending on his levels. If anyone can please assist any amount will be deeply appreciated to help off set the cost . I am out of work bc I can not  leave him.  Thank you and God bless
