Hiro may have an ear infection. =( I noticed Saturday night he was shaking a lot. But not the usual shakes. They were more "half" shakes. He'll slowly move his head side to side. I took a video of him and posted on "The Shiba Inu Forum". That's how I found out he may have an ear infection. I did a good search on doggie ear infection and he seems to have all the symptoms. Head tilted to one side, Scratching behind the ear, Shaking a lot. I called the Vet this morning and made an appointment for 2:00 PM tomorrow. Here is a video of him. Poor HIRO!
