To be specific - an emotionally and verbally (and financially to some degree) man, who keeps acquiring dogs that cannot be adequately cared for. A man who has a large number of children and an unwell wife who is at the end of her tether with the endless stream of dogs.
He gets bored of them within months, then keeps them in a cage under the stairs as they are hopelessly untrained, then rehomes them. Time after time after time.
This is a nasty sign of what he is really like under the affable bluster that most people see, isn't it? I believe him to be abusive as I believe what his wife tells me (we are friends) but generally people think he is great 
Is there any way to try and get through to such a man that he needs to stop getting dogs that he cannot and will not care for properly?
