Doggie Post Traumatic Stress Disorder...

We are at a loss with what to do for Buster. Quite awhile ago I posted how scared he is when we make shake and bake chicken. Well that has expanded to us putting any form of chicken in the oven. Its gotten so much worse since the night we had to be evacuated. I know that snuggling him probably encourages the behavior but a the same time we can;t let him get to worked up becasue he could have a seizure... what a mess. If anyone has any ideas please share them... sometimes it helps to hear from some one on the outside looking in.
