I did it a very long time ago in my 20s then I became a groomer because I was over doing necropsies on puppies.
There was a black lab puppy that came in that someone got for Christmas that got a hold of rat poisoning. We did everything for that poor puppy and I went home thinking about that dog and woke up going into work happy to see the dog to see how it was progressing... It was dead
I put in my two weeks that day. seeing that family the next day broke my heart into 9 million pieces.
We used lidocaine in the syringe though. I have used lidocaine that's in the aloe products for my animals because it is non-toxic.
