I'm not sure I see how something that is produced commercially is, by definition "bad for the animal". To give AoZ credit (and I'm not a spokesperson for them, or involved in any way) they do at least have an ethical policy statement on their website, which I've not seen anywhere else in this genre. And the fact that they operate in a country where this is legal suggests that they will try to operate according to that policy, rather than just posting it as a bit of greenwashing (or whatever the equivalent is here). I would have thought that something produced where the animal is well tended for, not coerced or restrained in any way, but where the owner hoped to sell the product, was preferable to material produced for "home use", in a back-yard, where it's tied up and there's no oversight whatsoever of the person producing it, or how the animal is treated.
My original question was related to the fact that AoZ do seem to be trying to improve the conditions under which all participants operate, and I was interested to see if there were plans to produce equine material to the same production standards (camera work, lighting, etc) that they have recently applied to their canine output.
