I have never had a pet that suffered from anxiety. However, when I was a support working providing support to a woman who had suffered a stroke I came to see how anxiety can stress a pet out. I had only been providing support in this particular couple's home for 3 or 4 weeks when we had a stormy day. It is lucky I love dogs and am not afraid of them because suddenly there was this border collie dog on my lap burrowing her head under my arm! Her owners ended up getting medication to give her when there were storms.
