Leigh, I was interested to hear you have trained your dogs to bark on command, I have often pondered on this but didn;t want to attempt it with my dogs previously as they tended towards being vocal anyway - 'nuff said LOL!!
I have heard that putting a behavour on cue means that the dogs never do the behaviuor except when asked, thus it is then under the onwer's control. Could be useful with a dog that barks too much.
HOwever, i have also heard the exact opposite, that it can make something like barking worse.
I would be interested to hear of your expereinces/thoughts on this one!!
