I've just read all your posts to Megan terrier and she thinks you're all nuts. :0)
When I sing at home, she just quietly takes herself off to another room......she knows she can sing better than any mere HUMAN.
When the new puppies are old enough to walk, I like to stand the guitar up on end,the nosey pups will gather round to have a look what it is. I then gently strum the strings. After the first fright they push their little noses onto the sound board to feel the vibrations and wag their tails like fury.
