Help Beau Robert's get out vet hospital

Hello, My name is Angela (Angie) everybody calls me. My dog 8 year old shih Tzu weights 21lbs was  attacked by my friends pitbull this afternoon. And he is fighting for his life at Med Vet in Metairie, Louisiana.

It's my friends dog pitbull who Im staying with that attacked my little 21 lb shih Tzu today his dog grabbed my dog by the neck and started shaking him like a rag doll side to side hitting kitchen cabinets, fridge, chairs everything blood, urine and stool was slinging everywhere. I'm screaming and hollering to death. I reached my hand in between Bowie and Beau but Bowie was biting my dog and got bite really bad. Brought Beau to a vet they couldn't help they couldnt take animals that needs emergency care, So they sent us to Med Vet in Metairie. They needed $2500 deposit up front before and test, Labs, xrays, scans but tomorrow we have to come up with another $2500 up to $7000. I tried breaking them up and his dog bite my hand I just got back from hospital been there 6-7 hours to put 8 stitches in my hand. I came home from work the Lpn was her taking care of his special needs child and I walked in and said Ok Bowie got outside to potty first before i let my dog Beau out our room to go potty so he did. I was standing 10 feet from the steps in the kitchen and i called Beau to come inside well Bowie was in attack mode grabbed my dog weighting only 21lb throat and started sliggling him like a rag doll blood,urine, stool and water going everywhere because the Lpn thought spraying water would make Bowie stop. It didnt not at all. I'm screaming and hollering so is the Lpn i tell her to call my friend it didnt go through right away. So I'm trying my hardest to get Bowie to release Beaus neck all while i didnt realize Bowie bit my hand badly and i still couldnt release my dog. My dogs eyes were literally crying I'm screaming for Bowie to stop as he still continues to bite harder and got a better grip. Finally my friend works with his k9 dogs he took his training pole because he is a reserved police officer and knew what to do. By that time my dog was lifeless hanging on for deer life. I pick him up in a towel blood, stool, urine, water everywhere. Now Beau is fighting for his life. The vet said in order to have xray, 24/7 to have a fentanyl drip in the iv, antibiotics, labs, and other stuff its $2500 deposit plus to keep him in icu for just tonight to see if he improved or a miracle happens over night we can get a call from them between 7am-9am on an update but they believe he has a broke left foot or paw because he holds it up and a miracle happen really bad when we move him. Bowie chewed at his juggler vein not sure if juggler vein was pitched or punctured it without proper. Couldnt find that out yet because Beau neck is too swollen right now. He has been my emotional support dog since I lost my sister in 2017 so it's been hard. I just need help with donations. Here some photos
