my labrador keeps on barking at my wall and thin air it's so wierd wat do i do

Get the priest in!

Lol, only joking, I'm afraid I wouldn't have a clue, hopefully someone can help.  Good luck.

Maybe he can hear mice or something in the wall?  What do you do when he does it?

It could be that it wants something to happen and is too polite to bark at you directly. Try giving the dog more to think about, like hide and seek your dinner or use a feed ball to feed him, more training and fun things to do should calm an active mind.

If he is old then ignore the above and just accept he has gone a bit gargar.

we comfort her and her there's nothing there

by comforting her you are rewarding the behaviour and encouraging her to repeat it.  The rules are a) ignore what you can ignore (ie - there are no safety issues or the behaviour will disturb/interfere with others) and b) distract from that which you can't ignore.  Obviously in this case you will have to distract her (unless you live in the middle of nowhere with no neighbours).  Does she have a favourite toy that you can keep away from her for a while?  Then use this as a reward for her coming when called, get her to perform some 'sits' and 'downs' and then reward with a game with the toy - by then she should have forgotten about what she was barking at, and over time it will stop being a habit.  The longer she's been rewarded for it, the longer it will take to train her not to do it, and she may well start doing it more if you are not rewarding her (known as an 'extinction burst') because in her mind, if what worked before stops working, then she must need MORE to make it work...........

HTH

It may also be something as small as an insect or even something burrowing that's setting her off - a dogs sense of hearing and smell is sooooooooooo much more acute than ours that we can't really say that there can't be anything setting her off.......

Our younger girl used to bark at the fire when she was a pup, we were told she was either trying to warn us about it or wanted to play with it! We made sure she always had something round her neck and very time she did it we jus got hold of her snd sat down until she calmed. If she carried on barking more than twice more we put her in a safe room on her own. Now she will stand very close to the fire but doesn't bark at it. I'd be careful that it doesn't turn into a bigger problem, some people may think it's funny, giving the dog attention and making it worse.
This is my opinion but I would sort ot out sooner rather than later, good luck.

My yorkie does the same...not barks at the wall..just barks sometimes for no reason...also when I let her out to "go pee" she runs out barking at nothing then keeps on- then stops and comes back in....I never really thought about it though. I thought she was just "chatty" (yorkie yappy dog).

Lol,

I always thought my mums Cairn was trying to frighten the big nasties away before they realised how small she was :D :D

Where I use to live, in a development of 5 and 10 acre tracts, I had a neighbor who lived on the 10 acres beyond mine and my next door neighbor's 5 acres. Their house, in other words was about 900 - 1000 feet away. These people raised champion Irish Wolfhounds and they had about 5 or 6 of them. They loved their dogs and were very kind to them....spoiled them rotten. But those dogs at times would all set up to howling and barking. It was loud. If I was outside, sometimes I'd hear one of the owners holler out their door at the top of their lungs, "shut up!!!" And by golly....they did....all at once, immediately. My Chi's sometimes get to yapping outside and there's no one coming. I don't know what they're barking at, but there's probably some noise in the woods or some dogs or kids way off in the distance. I don't much care. I holler out the door, "QUIET!!! ENOUGH!!!" And that's that for quite some time. LOL. They haven't suffered any deep seated psychological torment from holding in their feelings of my not understanding what it is they're barking at. But they have learned that enough is enough. LOL.

I'm sure to your dog it isn't "nothing" - copper barks and whines at things all the time, indoors and out and there is honestly nothing there - well nothing that I can see anyway.  He usually quiets down when I talk to him.

Last weekend I was in the Borders and walked past a little shop that sold hardware etc.  They had a "cat" doorstop (made of iron or something but painted) and copper was convinced it was a real cat.  He was going bananas to get into the shop and even when he had sniffed it 10 times and pawed it, he still wasn't convinced (thankfully he didn't lift his leg on it :D).  Gave all the tourists a good laugh though!  And he even had the gall to walk away, turn round and growl at it :D
