RE: Sportdog 1200
Actually, it's working out really well. I haven't used it often lately because she got spayed Thurs so everything has been on leash. But before then it worked really well. If she gets into an area that she's not allowed in, a nick will get her attention, the second nick and she'll come running.
Actually the first day she just wore it. The second day, two or three nicks. So, I used it maybe 7-8 nicks a week total. The size doesn't seem to bother her.
Congrats on the Tri-tronics G2. IfI didn't get a good deal on this, I would have gone with the G2.
