Everytime I sneeze our dog rushes to me, hurls herself in my lap or if I'm standing jumps up on her hind legs and presses her face against me. I can be in another room and she'll still come racing in to check on me. Even when she's sure I'm alright she stays really close for at least 10-15 minutes.
i had a sneezing fit earlier - 22 sneezes in a row and she was horrified - eventually she slung herself across my chest and nosed at my face - not sure it helped stopped the sneezing!!
I've never known a dog react like this before. I've known some that might be said to look mildly concerned but she's clearly very worried indeed
