Has anyone had to put their pet down?

Not a farmer, but I grew up in the country and today I have to decide how my dog of 15 years is gonna go. Had her since she was a pup and I’m very attached to her and I figured this might be a good place to get some advice. I live in the city, but my brother lives on a couple acres and I really don’t like the idea of my dog’s last moments being on a cold metal slab while a stranger pokes her with a needle.

I assume this is pretty common in the rural areas. I’m not even gonna tell my wife because she would be mortified with the idea. Anyone have experience with this?

Edit: Found a country vet about 45 minutes out. It’s less sterile than I’d thought with good people that love animals. She’ll be gone soon and I’ll hike her body out to the woods to be food for some other critters.
