I gritted my teeth and watched a few of John Cadogan's videos - he's great when he just talks physics and engineering, but when he tries to be funny, he just sounds like a bit of a merchant banker. Anyway, one of his rants - https://www.youtube.com/watch?v=_RANf_yUxZs&t=1380s - was on why you shouldn't try towing 3.5t with a tow vehicle that's lighter than 3.5t, which is commonly the case as the GCM of diesel utes, for example, tends to be around the 6t mark. During that video he covered some of the effective differences between dog and pig trailers, which lead me to wonder if dog trailer existed for sub 4.5t GVM vehicles (i.e. drivable with a car licence).

Turns out Googling for dog trailer gets you a lot of trailers for carrying dogs, but it did throw up this one from Dingo:

But I haven't come across any other examples, particularly not in the more useable 3.5t range...
