Since we don't have many thunder storms here in Southern California, I did not know what to expect with Daisy and Perry when a thunder storm did arrive. As luck would have it, we had one about three in the morning.
Perry was in his crate which he loves, he even takes his afternoon nap in it, didn't hear a peep. Daisy was sleeping with us and she slept right through it, didn't bother to lift her head out of the covers., so I guess all is well here.
