This link describes the symptoms I have been having. Three times this past month I stopped in the middle of running, walking, or just getting up from lying down, and started screeching (not the normal shiba howls when greeting owners), like I was in extreme pain. I would get into a catatonic state physically, with head contorted in a weird way, legs straight up, screaming. After 1 or 2 minutes of unbearable screeching, I would get up, walk away as if nothing happened. No limping, or any residual symptoms. My owners rubbed me all over to make sure I did not pull a muscle or broke a bone, but absolutely no reaction. I would wag my tail all happy and run around like the episode was nothing.
Anyone heard of other shibas doing this?
Please ask around. Thank you!!
