Two of our neighbours leave their dogs out overnight and fairly often we are woken up by barking in the middle of the night (usually when they see a cat!).
When the dog was a puppy, we had to speak to the neighbour about the barking and he was apologetic and said he would lock the puppy in his kennel!
Aside from the barking, leaving your dog out over night and especially locked in in kennel doesn't seem very kind to me but not sure if this is a normal thing to do with dogs as I've only ever had cats.
We don't often hear them barking in the daytime so I think they have them inside during the day and the dog of the neighbour that we know is walked and looks happy and healthy so they are not mis-treated or anything but just wondered if leaving a dog outside all night is common.
