I know it's rude to post several times the same thing, but I just realized that this question should be here rather than in the ask a mistress section, so sorry about asking again.
2 weeks from now, when my Princess returns I am going to wear a Petsafe shock collar for big dogs (over 25 pounds, I'm 5 times that big so I really didn't think there could be a problem).
Do you have several times as much hair or fur to act as insulation too?

It uses two 3 Volt batteries, but I have no idea of the current. It has 8 levels of correction. I just saw (searching "electric" on the forum) that some people use "TENS" units : whatever these devices exactly are, what is the current used by these devices ? How much would be a safe current ? (I have something to measure the current, in case the user manual doesn't specify). I read somewhere on the internet that 5 mAmps is a reasonable limit (10 mAmps being really strong). Is the intensity of the shock measured by the Amps alone, or should I multiply Amps * Volts ? The later seems more logical to me, but I didn't find anything about the voltage...
Electrical shock is a complex subject. Much depends on frequency; the higher the frequency of the shock, the more the current travels on the surface. DC will cause a deep single spasm, and usually knocks the victim free of the contact. The most dangerous frequencies seem to be in the 50 to 60 cycle range. People have used military surplus field phone hand cranked generators to good effect reportedly in the Gulag, Siberia, and Iraqui prisons before 'we' went in. In that frequency range, the current will often travel very deeply in the interior of the body.
Multiplying Amps by Volts gives you Watts. The damage to the tissues is mostly the result of current passing through, and that will vary by tissue. Current is amps, and is a measure of how many electrons are being pushed through a conductor per unit of time. It is the electrons passing through and messing up the electrolytes in the cells that causes many of the problems.
Some of the injuries I found listed on resulting sites when I used "Electrical shock effects" as a search string included edema, tissue damage, bone fractures, muscle and tendon tearing, coma, and death.
As for the fact that you "have something to measure amps" --- how would you measure this amperage? Do you know enough about electricity and electrical circuits to know how to measure the current reliably, as applied to your thigh or wherever it is placed? If not, you might run some major risks. Biomedical electronics is a complex subject, and not one I would explore on my own body.
quote:
Is it true that the collar should rather be worn around the thigh instead of around the neck, for safety reasons ? I thought about wearing it around the thigh, but only to be able to wear it any time.
Yes, it is probably not as dangerous to break your leg as it is to break your neck, but remember, in EMT school one learns that a femur fracture is considered life threatening as well.

I do want to improve my obedience, but I don't want to damage my health in the process (and my Princess doesn't want that either).
Good thought!! Staying healthy is a good thing.
Personally, I wouln't use anything designed for use on another species, especially not something that works on the principles of tasers and cattle prods. TENS (Transcutaneous Electrical Nerve Stimulation/stimulator) units work on similar principles, but are designed to penetrate and stimulate within a tightly controlled range. You won't find that in a dog collar, I'm afraid.
Do some careful research before embarking on this venture. Err on the side of caution. My advice: Don't play with this stuff. It's not worth the risks, from my viewpoint.
