Is there something wrong with sport dog I don't know about, or are dogtra collars just that much better? I just got the sport dog 425s and so far it's been working fine for me.
I would never have changed had I not been able to get one in my hand at a show recently. The fit of the transmitter to hand is the thing that actually pushed me over the edge.
Interesting to hear that folks have had such poor experiences with SportDog. I've owned an SD 1875 for several years (multi-collar), used almost everyday, with zero issues.
