Same but my dog is 2. I sometimes read rainbow bridge stories on r/dogs and then just worry.

I did work experience as a 15 year old hoping to be a vet. The RSPCA brought in 30 rabbits from an old woman's house who had died. She'd been keeping them all over the house - in the oven, in the microwave, the bathtub. They were all very sweet but some of them were in a state. Matted, injuries from fights, nails overgrown and curled into their own feet.

I had to hold about 10 of them as they got put to sleep. The rest were treated and rehomed.

I'm a human doctor now. I couldn't cope with playing an active part in death.
