E Collar - Aetertek
I have Aetertek E Collar (AT-218S).
When I first try it with the first stimulation level it seems as it too much hurting to my dog (because he screamed when I use it) so I stop using it for a while.
I know it's the first (lowest) stimulation level because I used a tester before trying it on my dog.
Does anyone familiar with this E Collar?
