that would be the same as saying if a dog gets loose and attacks another dog that dog owners not responsible . It is the owners responsibility to keep the horse confined it so that it can't injure anyone else . If it had been a gelding it would not have went after the other gelding like that . That is what gives stallions a bad name a lot of people won't board a stallion . If you choose to send your kids to school and other kid hurts him he's not responsible becaus. E you chose to send your kid there ?
They were in a public barn if I am not mistaken... that means the bo is liable for the horses getting loose seeing as the boarders pay to have them keep there horse safe. Which in either case is not happening because we have neglected animals and animals getting loose there...
Out of pure niceness and etiquette the stallion owner could contribute to covering som/all of the bill but they are not required to. The stallion owner pays for his horse to have a stall that will contain him and if he got out after being secured in there I would think that's a bo's liability.
Same for dogs if my dog was at a kennel and injured another dog that is the fault of the kennel not me. My dog was under the supervision of someone else. If I wanted to be considerate I would offer to pay atleast some of the costs but I would hold the kennel responisble for not watching my pet better under there care.
If the pet however was under my direct care and injured another then yes being owner I would be totally responisble to cover all costs.
As for kids hurting another kid while at school.. firstly I would be ticked at the parents for having an overly aggressive/spoiled child and ticked the school for not providing a safe environment for my child to learn when I pay taxes/tuition to send them there.
Just my 2cents on it
