Hopefully it’s just something more benign like idiopathic vestibular syndrome. IIRC, the dog’s inner ear just goes bonkers for a bit and the brain gets so confused the poor beast pretty much just stops in its tracks for a bit. The last time our dog had it, she went limp on one side and tipped over like one of those fainting goats.
We found a new house to rent. It’s almost as if someone asked us what we wanted. Big “game” room that will become the sewing studio, a guest bedroom, an office space for me, a half acre yard with a Chihuahua-proof fence, and a roughly 20x20 foot outbuilding with power that will become my workshop. Close to my office, close to Faire and a lot less than we’re paying now.
