Nightmare on Puppy Street

I'm currently dogsitting and I straight up had a nightmare scenario happen last night. I went out to a comedy show and stayed out 45 minutes after. I get home and this puppy (an old puppy, 14 years old to be exact) was barking, but so rapidly and violently that it actually sounded like she was dying. I made m

y Fiancé leave so I could get her calmed down. I took her outside cause she seemed like she wanted to go, she kept barking/panting/dying outside. I bring her inside and take her upstairs. In my head I knew she was just pissed off at me for leaving her confined to the main floor when I left. So I get her upstairs, she continues to bark/pant/die violently. At this point I am terrified she is like choking on something in her airway and is struggling to breathe.

I'm opening up her jaws to see what is back there, I'm smacking her sides to get her to breathe, I'm pushing on her throat (which I have done with my own dog and saved his life with) to try and get whatever is in there out. No luck. Still barking/panting/dying. I call my fiancé twice. He does not answer. I remember his phone is dead. I don't want to call her parents, its actually midnight and this might not be a death scenario. I go to call the son of the parents. I don't have his number. Fuck.

I get her on the bed to maybe calm her down while I figure this out. After I hoist her onto the bed, she starts to slow down on the bark/pant/die. I lay down with her and she slows down to a complete stop. Breathing a little heavy still- she was literally just bark/pant/dying. She calms down to a complete silence.

Puppy was SO ANGRY that we weren't in bed that she had a seemingly life threatening event over it. I think this is the most dramatic puppy I have ever encountered. I set alarms throughout the night to verify that she was still breathing, but other than that we are entirely fine this morning.

We survived. Who knows what will happen next? Puppy Dog Toy Massacre?
