Tempus Fugit

For a dorsal hitch sulky you need a harness designed for a dorsal hitch with a padded saddle pad to avoid the shaft hitting the dog's back: Chalo or Dog scooter

The "C" tick is a radiocommunications compliance label administered by the Australian Communications & Media Authority. To get the C tick an electronic item needs to comply with a particular Australian Standard (the number of which I can't remember) which is supposed to guarrantee that it won't interfere with other radio communications services. You can find more details at ACMA. In the USA the regulatory authority is the Federal Communications Commission (FCC) The rules for short range devices such as e-collar transmitters only require the importer/ seller to certify that the equipment complies. No Australian laboratory testing is required. Given that the major e-collar manufacturers, (Dogtra, Tritronics, Innotek) export to many countries, you will probably find the US manufacturer will ensure that equipment complies and will affix the C tick or whatever regulatory label applies to the country they are sending to the equipment before dispatch. It wouldn't be done by the local dealer. So you may be able to buy equipment direct from a US manufacturer that is compliant but as has been mentioned earlier the advantage of buying from a local dealer is the ability to easily phone the dealer and berate him and get warranty service if the item breaks down, which might prove difficult if bought overseas. In practice, remote control e-collar transmitters are only used in short bursts so it would be difficult for them to cause interference or be detected causing interference. On the other hand, signals from ínvisible fence' systems obtained from a local dealer and supposedly compliant come through loud and clear on my AM radio. Hopefully now that digital radio broadcasting has commenced since last week we will soon be able to ditch AM.

Au revoir, my sweet beautiful hawkesbury princess. When I left you that morning I didn't realise you were going away across the bridge. As the song says 'I didn't mean to be unkind'. Forgive me.
