If you are just concerned about living next to a slaughter house you could also solicit information from people who live next to other types of slaughter houses (pigs, cattle, whatnot). I'm pretty sure, from the outside, one is not much different from the other. When I worked for a material handling company I had to go to a pig slaughter house to service their forklifts. From the outside it didn't look or smell much different from any other plant I'd been to. The forklifts were kind of funky tho LOL
As for your horse being stolen to be sold to a slaughter house, I guess anything is possible. Both cattle and pigs are stolen for similar reasons, so I guess the same could apply to horses, However, I doubt your proximity to a horse slaughter house would increase your risk.
Foxhunter's comment has reminded me, I want to check into the whole microchipping thing!

Reason: I improperly used both slaughter house and processing plant to mean the same thing. Thanks KarrotKreek!
