Our 2yo Border Collie girl has started doing something really strange. When I am putting on my eye makeup, putting eye drops in my eye, using my ventolin inhaler and taking cough medicine from the little medicine cup she goes totally crazy, barking and jumping up at my back. Do not know why she is doing this. It has come to the point where I need to do all of this behind closed doors. Any ideas as I am really perplexed?
