Dogtra 1 Mile Training Collar-2 Dog

I walk multiple small dogs and this trainer works for me. It controls 2 dogs each with a button. There is a toggle switch that chooses between nick or constant. I use nick. The transmitter is smaller than the Tri-Tronics model.

The stimulation is good and the level selector is stable in that it won't get moved

accidentally to another level.

It comes with a lanyard and the build quality seems top notch. I use Velcro collars as

the included collars are too big for my Chihuahua mixes.
