How is that owners of dogs that bark constantly cant hear their dogs barking?
If you have ever lived next a dog that barks, you know just how maddening it can be. Much of the time, these dogs bark at 5am or midnight. Something about not sleeping because of a neighbors dog barking for weeks on end makes me irritable.
If find it ironic that your brother does seem to care that his dog is bothering the neighbor with noise but when the neighbors makes noise (cusssing, barking, etc) he is offended.
It seems the solution is to control his dog...
All animals are equal, but some animals are more equal than others.
