8 Months Starvation
This is sad-- a woman was paying $250/month for the feed and care of her elderly TB horse. However, one day the caregiver quit feeding the horse without notifying the owner, but kept taking the payments-- and the starvation went on for 8 months. The 24-yr old ex-racehorse weighed 500 pounds and ranked a 1 for body condition when he was rescued by his owner, but he's now on the road to recovery.
I know a lot of people aren't comfortable trusting others to feed their horses, but I've never heard of a case this extreme. Ironically, this happened in a town called Plain Dealing.
