In the past couple of months 1st Stuart and now Rooney do this strange thing where they get right in my face, place their nose almost on my mouth and very gently sniff my breath for several seconds. Rooney has also done this to my ear a few times. Dh has seen them both do it and he agrees that it seems really strange. Do they think my breath is bad? I have heard of dogs being able to detect illness but I feel fine - so what gives? Any ideas or does anyone else have a dog that does this?
