Help me save my best friend’s life

Me and my boyfriend met Ango only this year. His owners didn't take care of him, he would keep on running away and that brought him to a dog shelter. When we brought him home he became our best friend. We did everything together, we would go on trips, we would visit our friends and family together, we would take him everywhere and everyone loved Ango. Ango is a very nice dog, he loves giving hugs, he shreds any toy we buy him but he takes care of a my teddy bear that I gave him and he's very gentle with him. Now we are taking care of our dog Ango just like he is of his teddy bear. Ango was recently diagnosed with encephalitis. We've already paid a lot of money in order to determine his disease and treat it. And... We have run out of money. We've started borrowing money but people around us also don't have any more money to lend us. That's why I am searching for help here. Ango is a great dog who was treated bad by his closest people and now he was living a happy life but it only lasted for a few months. I believe that he deserves a lot more happy days, months and years to live. He's a young dog (around 2 years old) and we have so many things planned that we want to do with him. I really don't want money to be the thing which will say if Ango still deserves to live. Please help me save my dog because I'm not capable of doing it by myself anymore. We aren't sure how much money we will need for his treatment because his illness was at a really bad stage but I hope that he will get better really soon. Thank you for your time and help.
