If they are only concerned with being able to see the dogs batonga wongas waggin in the breeze then they could get some Neuticles put in. This is for real...they are prosthetic testicles for dogs. When the dog is 'clipped', the nuticles are put in the sac in place of the junk and they don't shrivel up. They are made of some sort of soft rubbery substance so they are not uncomfortable for the dog and the male owner's macho can stay intact too.
