I'll just say one of the top in the nation. :]
Well my dogs ears are totally down, as you can see in my avatar picture. They sometimes come up when he is attentive. He is going to be 6 months this 18th. Your dog is so cute! I think his ears are cute with one of the tips down.
I'm not worried about it, but it's just that they stay down like, 95% of the time. So I am going to get them taped. Haha, I know, it sounds weird but I asked around and people think that I should do it. It never hurts to try.
