Why does my dog bark at nothing?

Answer 1

Your dog is communicating something. The dog hears, sees and smells better than you probably and it probably is something. My dog barks once for us to let him in. He barks when his buddies go by.

Answer 2

It would be difficult to answer this without knowing your dog's situation but constant barking of a dog when there is nothing to bark about is usually due to the dog being bored or frustrated. So, if a dog never gets to go outside and see new things or get any exercise, this could be a way for them to get rid of extra energy or just to keep themselves busy.

Answer 3

he probably hears something like annother dog barking

Well....if it's in your house they are probably saying that there is someone outside or that there is an animal, like at night, a raccoon or possum. They could also be hearing stuff that you can't hear, since they have better hearing than us.

Answer 4

They actually are barking at something. You may not think it though because dogs have keener senses than humans.

Answer 5

IF you believe in the unbelievable then yes if not then no he might be barking at something the human ear can't hear such as a dog whistle just an example

Answer 6

It might be that there lonely or they hear something. Another answer is that in Greek Mythology Melinoe goes around hunting people at night.
