The youtubers simon and martina from eatyourkimchi have a dog that they dye blue (not completely) but it's so cute! If I ever get a dog, I know I'll do this. :3
Well I think there's no reason to be particulary defensive if it doesn't harm the dog, and the owners take good care of them, they should be able to have a blue pet if they want to. Again, as long as it doesn't harm it and it is in good hands.
