Gilly is 16 months (when do we stop saying months?) and I've just resigned to the fact that she's a "chatty Cathy". She was realllly barky too. It drove me crazy! She's our only pet an she would bark at us when she wanted to play or was bored (and exercise did help with that) but sometimes shed have been on a long walk an was still barking, and she would do te same thing where she barks non stop at her choc lab cousin and harass him. The harassment hasn't stopped but we eliminated the barking inside with time outs. Problem was *mostly* solved in one intensive day! Every single bark got her about a 5 minute time out in the bathroom. If she barked while in the bathroom we gave her an extra few minutes until she was quiet. I think she was in time out for a few hours total that day. The next day she gave a bark, went in time out, and the barking has pretty well stopped! I think she's converted to whining which is annoying as well but less obtrusive and more easily ignored, depending on why she is whining (pee breaks or clean water requests don't get ignored, whining to go lie outside at 5 am does get ignored and she quits after a few irritating sleepy minutes). We also haven't been able to fix her outside play barking (like when she is barking at her dog playmates, trying to force them to play with her), but if it's bad an we think its offending the neighbors we'll bring her inside to calm down. Every once in awhile she will still bark but I'll put her in a time out again for a short time, even 45 seconds, and she gets back on track. I don't know if it matters, but someone told me when we do the time out, not to be angry or show any emotion, not to say anything, and just to grab her (often dragging her on the floor since she would flop down) and put her in, and not to say anything when we let her out - just open the door and let her out. We DID say calmly and quietly "time out" as soon as she barked hoping it would work as a threat but she never caught on to that. And I can't figure out the whisper command, but I'd love to!
