Woman who had her healthy pet dogs put to sleep

Just saw on the news a piece about some woman who had two dogs in quarantine for a number of weeks – on the news they showed the dogs as being healthy and happy, the people at the kennels pleading with the owner (who wanted to have her healthy dogs put to sleep) not to, that the kennel would try and find homes for the dogs/that they’d grown fond of them – then a few moments later, the dogs were shown to have been put to sleep, as that’s what the owner wanted.
Surely that is outrageous? If it’s wrong for people to be cruel to pets, how on earth can it be right for an owner to decide to have healthy pets killed (because that’s what it is, really – they weren’t ill or suffering)?

Did anyone else see it on the news? (Probably be better off if you didn’t, as it’s not a chirpy thought!)
