Do you think it's cruel to lock dogs in the house while you go to work, who then bark and bark?

they may not know this is happening. you may want to tell them. it isn't going to injure the dog's throat, but it is a result of stress on the dog. the dog may need some more exercise. maybe, if you're good with dogs, you could volunteer to walk it for them some afternoons.

It doesn't hurt the dog's throat to bark continuously. When dogs bark they're actually inhaling, not exhaling.

Try it: make a barking sound by inhaling. You'll sound much more like a real dog.

So you can rest your mind about that particular aspect of your neighbor's dog. It's unlikely he's being physically hurt by the actual barking.

It's still cruel to leave a pack animal alone for more than a few hours every once in a while. They can't deal with it psychologically. That's why it barks for hours: it's hoping to let them know where he is and that he's alone.

You could leave an anonymous note explaining that dogs can't be left alone for that long, but the owner will most likely ignore you.

They should make a driver's license level regulation for having a pet that needs as much care as a dog.

Very cruel, yes.

Dogs that bark continuously when the owner is away are usually going through what is know as separation anxiety. In most cases, you and your dog can work through it.

Offer to take it for a walk during the day? Mayhaps they agree. Either way, it's heartbreaking but people should be educated; even if they do nothing about it. Hopefully they will.
