You cant really compare serious peanut allergies which can kill with sneezing and the odd rash from being near a dog. People are only prescribed epi-pens if they really need them (trust me, even then they can be very hard to get hold of). But on the flipside, if an allergy sufferer claims they cant fly without something and they havent got their medication, it is their issue and they should be told they cant fly without it.
