"I was hesitant to go this route with my new dog, but after lots of research, decided it was humane and our last resort--she will not stop chasing the cat! However, the collar does not come with the free training DVD as advertised here, so I feel I am not using it correctly at this point.
The settings are inside the transmitter so to make any adjustments, you must open the transmitter, which is difficult and requires a tool or a coin. Then once inside the switches are so small that I can barely see them and I have great vision!
I am also unsure if the dog is even feeling the stimulation. I have raised the level several times and even used the boost feature, but so far, we are having no luck. I may need to trim some of her hair to get a better contact, but perhaps I would be having more success if the training DVD were here?
I suggest looking for a different collor, one with the settings on the outside of the transmitter at the very least!"
