Just read your post, it might be the same, Willow isnt scratching though. Weird as she stopped in her tracks whilst out at the weekend and turned her head quick but it seemed like she was then looking at her leg. She soon carried on and we thought nothing more of it, it might of been then that something bit her and made her jump however the two might not be linked. This time last year she had a few wasp stings in as many weeks but its not that although earlier prior to close inspection I thought it could be!! Weird. Hope Murphy is okay xx
