Too much barking
We got Tessa, a 5.5 year old GSD, back in June, and overall it's going great. She's good tempered, loving, gorgeous, gets along great with our other pup (6 year old greyhound mix), and is very silly. The only issue we are having is her barking, especially in the middle of the night (our other pup only really barks when someone is at the door).
If it were always *at* something, I would understand a bit more, but sometimes she will start to bark and walk around not looking at anything in particular, and she won't always listen when we say "no bark" or "enough." (maybe we have ghosts?) It sometimes happens while we are petting or playing with her, so this isn't some bid for attention. Sometimes at night she will suddenly bark like three times (you know, enough to startle you awake), probably at a car or something, which shouldn't be setting her off because cars go past the house all day and night! Anyway, welcome advice on curtailing the barking.
