First, my breed history...

Almost entirely Sighthounds:

Basenjis, Irish Wolfhounds, Whippets, Greyhounds & Borzoi, plus one Akita -- NONE of these were ever Barky ... Many lived into their TEENS without ever Barking even ONCE

Then I got ONE Dobie, and okay, she barks a bit (but not a nuisance) -- However, with the addition of my 2ND Doberman, I now have a daily Bark-A-Thon on my hands Early AM & Late PM

Due to the configuration of my House & Fence, plus having had the FIGHT SET-BACK last week, I take each dog out On-Lead to do their business SEPARATELY in my Backyard (the difficulty occurs during the 6:00 AM and the 10:00 PM pit-stops) -- While I have the one Outdoors, the other BARKS indoors ... It wouldn't really be a problem, except that I have NEIGHBORS in Close Proximity on all four sides of my home !!!

So, this morning I ordered two Educator BL 100 Bark-Less ecollars, STAT -- My Questions:

Has anyone here used this SPECIFIC product & if so, could you please share the details of your experience, Pros and (if any) CONS -- Thanks a Million...
