Thanks for the reply, Volcano. I would like to believe this pup doesn't have a problem, but he did get bitten, and the ear went down very soon after. And to me it doesn't look like a "soft" ear problem.
How long do you suggest I leave the ear alone before doing some kind of tape on it? If they go up and down, how long a time do they typically stay down while this goes on? I'm pretty anxious about it, as you can imagine.
