Step 1 - You need to determine how far away the barking dogs actually are so 
that you will know the amount of sound pressure you need to generate. To do 
this you can refer back a few months on the list where someone was interested in 
using a microwave magnetron to do long distance range finding.

Step 2 - Now that you know how far away the dogs are, you - - - Oh wait, 
there is no step 2. Apparently the dogs are done     barking.

OK, so I thought I had an idea, but I guess not.
