I prefer dobes with a nice elegant crop, or a nice short almost "battle" crop.
For bull breeds and CO and CAS I like the super short "working or battle" crops.
I LOVE a good looking short crop on AmStaffs, APBTs, Dogos, ect.
Docking, eh, it depends on the breed really. JRTs I definitely couldn't see with long tails. Aussies, I like all their tails, but I like the NBT and the longer NBTs as well.
I don't like Dobes not docked either, lol. Boxers I like cropped and docked. I do NOT like boxer tails for some reason. Though I make exceptions for certain dogs that it actually looks natural on, and not like it was stuck on as an afterthought
I really do like the CAS crop and dock. For some reason, it's super appealing to me, and without it they look odd. One day when I have my horse farm, I will have a pair of CAS.
