WD-40 IS NOT diesel! Come on!! Or even "basically diesel"...do some research.
It can safely be used on any animal. I have personally used it on my horses tail when it was matted. Now, having said that, do I want it drenching my horses' skin...maybe not as it does say not to have it touch skin as it may be an irritant.
