I had a horse colt boarded at a persons property... That person put sick horses in with mine and he got a cold... we brought him in and gave him some antibiotics...I came back the next day, my colt was looking better so I wormed him... I came back that afternoon and he was wobbling, sick and didn't want to move... the property owner then told me he had already given my colt wormer intended for use in beef cows... I called the vet and hauled my colt to him... he said it was toxicosis, and that too much wormer made him colic... the vet put mineral oil in my colt to see if he could get things moving again ... two days later my colt died as a result of colicing.. Since the property owner did not ask or tell me that he had given my horse wormer before he did or before I wormed my colt and did so wothout my permission is he liable for him? I called him and told him we needed to talk and he threatened me.. He said if i tried to sue him bad things would happen..
