Hello and welcome. My name is ***** ***** I have been in the dog field for 25 years. I am a Therapy Dog & AKC Evaluator/trainer/ as well as an assistance/service dog trainer, specializing in behavior. It will be my pleasure to help you today. It may take a few minutes for me to type a personal response or type questions regarding your situation. Your patience is very much appreciated.
For some it is the static in the air for others it is the sound. Dogs do not know what a thunder storm is, how it works, only that it is sporadic and loud. Because it is an infrequent it has no constituency. If you had them every day for life then they would be consistent in a dogs life and maybe not feared so much.
To help you can do much of the same things one does for separation anxiety.
Offer a calming space, play calming dog music, turn on a floor fan to minimize noise, give some melatonin the day the storm is expected (unless on other medications).
some will do something fun with the dog so that the dog begins to associate storms with fun things happening. Much depends on the time you have. But ecasue they are so sporadic, always being home with the dog is uncertain to do such fun things. Buying a CD with thunder storm sounds on it and playing that daily to try to desensitize the dog to the sound can help. Start off at a low volume then gradually increase it.
Melatonin found in drug stores by vitamins Use only if not on other meds. http://www.petplace.com/article/drug-library/library/prescription/melatonin-melatonex
