It happens all the time. poor things. If they're lucky they get someone who has a bleeding heart (present company included) and will love on them forever. But unfortunatly most don't.

We had a neighbor try to drop off four horses in our pasture because they were moving. We had foals out with some pretty protective mares, saw them, said "WTF?" and they actually said "Well we figured four more would be nothing to you guys".

Uh, theres only FOUR horses in this pasture. FOUR plus FOUR equals eight. Thats x4 the vet bills. Be a responcible adult you freaking tool.

Or how about my friend. She had 40 acres, had a TWH stud left on her property. At that time she was just a newb. Took care of said stud for a long time, got training on him, battled for papers (apperently he was really well bred, and he was honestly one of the nicest TWH i'd ever seen...though not to breed type. Very solid and almost andilusiony, still gaited though)

The owners came back once they found out the horse was now trained and cared for, wanted him back! This was like 7 years later. She handed them a bill and said "ok, when you pay for vet, farrier, board and training for the past 7 years".

People are knobs.
