"Danny come and look at this air biscuit, it looks like a piece of cheese on toast in a washing up bowl"

Much worse than the dreaded SBD, an Air Biscuit will follow you, get in your clothes or even linger in the seat cushions. The taste you get from walking into one is like eating smelly cheese while breathing propane. They are not gender or genetic specific. A dog can wreak havoc as well as any human.
