So i work in a vet clinic. im not a vet or a very nurse, im just a receptionist. So i dont examine or treat the pets. But tonight we had a old dog who was blind and we had to put him to sleep. The vet and vet nurse were having a hard time holding him and putting in the catheter so i was brought in to pet the dog and comfort him. Anyway, when the catheter goes in, its painful and the dog yelps, its really unpleasant. The dog was blind and couldnt see us or what we were doing so he was freaking out and biting. Long story short, we ended up putting the dog to sleep in my arms as I was patting his head. He was breathing one minute and the next he just stopped. Its really emotional. Its sad and hard to deal with. Ive never seen life leave a living creature before.
