have you tried on of those calming plug in thingys? (sorry dont know what they are called) you can get them from the vets, my mum and dad used to use one for their bichon frise 'Winston' who had terrible fear of storms and fireworks etc? also i have heard that using a C.D with the sound of thunder etc can help, apparently you start leaving it on really low and then sensitise them to it gradually. Also try not to give too many cuddles, when they are scared because apparently this can reinforce the behaviour just gentle reassurance instead apparently... (i have been doing a lot of research lately can you tell?
)
