[Dailydrool] training question

[Cheryl Stafford]

Radar, 19 months, has turned into quite a barker at the neighbors.  If 
he is outside and sees them, he will run to the fence and bark, bark, 
bark.  I need to train him not to do this.  Any information/ideas would 
be greatly appreciated.  I was thinking if I carried treats outside and 
when the barking began I would call him away from the fence, have him 
sit and them give him a treat.  However, is this rewarding the barking 
or the coming away and sitting?  If he comes and sits for the treat, 
eats it, them returns to the fence to bark do I call him away and repeat 
with the come, sit, treat?  He has met the neighbors, sniffed them and 
accepted pets, but then he starts the bark, bark, bark again.
