Anyone else?

I don't know what makes me ask this, but have you had a checkup? This reminds me of the dogs who detect cancer or another health issue in their humans.

I think it's the fact that you, the alpha, have compromised your
position with the dog by lowering your body to his level..It's a invitation
to play for the dog and he gets excited. It's better to interact with him
while you are seated on a chair, or standing.
