Well, maybe some others found on the web.

If the dog is kicking too much, you can slightly reduce the condenser in the red circle.

Its role is to signal the operation of the device and the moment of the flash corresponds to the high voltage pulse at the output of the device. I don't remember exactly, but it seems to me that the device was designed to be powered with 6V. at a voltage of 4-4.5V, it is still very stable, the current consumption is around 40mA. I don't know if the transistor will withstand 12V. Certainly in terms of voltage, but if the power will not exceed its capabilities, I do not know. I am of course considering the BC211 transistor. This transistor or equivalent is cheap, so failure will cost you littlethis neon bulb on the secondary winding can be, for example, from a switch with backlight or from a power strip ??
TL;DR: A safe DIY electric fence for dogs needs 2 000–5 000 V pulses [Elektroda, zybex, post #16050060]; "the important thing is that it is a very short-lived impulse" [Elektroda, zybex, post #16050060] Use a 12 V battery, an ignition coil and a 555 timer to generate ~1 pulse/s.
Why it matters: Correct pulse energy protects the dog while stopping escapes.
• Pulse voltage: 2 – 5 kV recommended [Elektroda, zybex, post #16050060] • Max pulse energy: 5 J (IEC 60335-2-76 safety limit) • Typical pulse width: 50–100 µs (IEC 60335-2-76) • Basic circuit draw: ≈40 mA at 6 V [Elektroda, Zygaqra, post #16639294] • NE555 price: ≈1 PLN [Elektroda, Rezystor240, post #16046325]
