I have never used a scat mat but while working with the behaviorist with Jazz he told me it was very important I get a fantastic recall on her. Her recall was good except at the large park that allows dogs off leash if she did not want to come to me she would look away from me and act as if she did not hear me. If she looked at me she would come but when there were gophers around she would look the other way and ignore me. His suggestion was to get a remote citronella collar. Jazz was a very sensitive dog and a shock would have been too much for her.
The very first time I used the collar we were at that park, I called she looked away then stuck her head in a gopher hole and ignored me so I hit the remote...omg it was so funny as she jumped so high up then raced to me and hid behind me. When she got brave she crept towards the gopher hole again not wanting to get close enough that that gopher could spray her again but wanting to see how he had done it.She was convinced the gopher did that to her!
). It took using that collar twice and after that she always came when I called even when she did not have that collar on.. I used it for other things like when she would race around frantic barking and trying to pull my young nephews out of my parents pool once again it took about two times and after that she would watch the boys but no longer get frantic about their being in the pool. That collar worked so good on her. Hopefully you will get the same results with the scat mat.
