<human>: Can you provide a brief overview of the text?

Long time lurker, first time posting. A black Labrador followed me home three and a half weeks ago. I called nearby shelters, hung flyers, put ads up on craigslist, and more, searching for his owner. After two weeks he was legally mine. Absolutely love this dog! He follows me everywhere and is really good with my kids. First things first, I scheduled an appointment with vet for vaccinations. 
     Two days ago Monty started having convulsions, eyes rolling and rocking, mouth twitching. I called vet and asked what it could be, and they wanted me to bring him in. This week we paid two of our monthly bills and are broke. I start researching his symptoms and realize they fit Distemper Virus. When I rescued him he had white conjunctivitis, runny nose, and reddish eyes. Vet said it was just allergies. I had mentioned to my SO how Monty was acting sad and depressed one day.(symptom) Also I usually mix wet food with dry food, when I ran out of the wet food I noticed he would wait a couple hours before eating it. (Lose of appetite, another symptom).
     It wasn't until he had the convulsions that I realized he was even sick. Later that day the conjunctivitis had turned green. I've been calling emergency pet clinics for two days, trying to find one that would see and treat him and bill me. Applied for care credit and was denied. Usually when I let him in from outside, he is excited and jumps on me, however tonight he was jumping, barking and bit me harder than ever. Other symptoms of wandering in circles, shaking head left to right quickly, and what is called chewing gum fit.
     I'm calling the vet again in the morning, hoping to persuade them to see him and bill me. This virus is fatal in 50% of adult dogs. Suggestions, advice, resources, anything that can help me save my dog Monty's life!!!
<bot>: rescued dog, has multiple symptoms of Distemper virus, broke until Friday, has a vet appointment scheduled for Saturday, scared he may not live to go to vet.
