Help save my dog!

As many of you may know my dogs are my life. We are currently trying to save my dogs life. I got home to find my fur baby hiding in my closet when i noticed something was wrong. My brother had to carry him into the car to rush him to the hospital with barely any breath left in him. Hes currently at the Emergency Pet Clinic in Temecula.  Dr doesnt know exactly what to diagnose him with. Obi is in critical condition to unknown diagnosis & the Dr. wants to transfer Obi to Internal Medicine to save his life but unfortunately we dont have the funds to do so. Please help me and my family out even if its with $1. Anything is appreciated

update: obi’s blood vessels are leaking & is currently getting a plasma transfusion & blood pressure dropped. Dr said hes showing signs of pain on his back legs. We got confirmation that its a rare disease especially for his age which is only 3yo. Drs believe it could be related to liver failure possibly caused by a stroke. Not quite sure as we are still waiting to get his test results back. Due to him having to stay night and days at the clinic and many tests our  bill is piling up  but we are not giving up!
