Paroxysmal episodes of abnormal movement consistent with a diagnosis of episodic falling in a 6-year-old Cavalier King Charles Spaniel (CKCS). Note the involuntary movement of the pelvic limbs in particular and whole body course movements. The frequency of these movements is very slow, unlike generalized tonic clonic seizures in which they can be much faster. Later in the video you can see a marked kyphosis in the dog’s back and dance-like movements (so-called chorea) in the pelvic limbs.

Myoclonic jerk that can be seen in the CKCS. The myoclonic jerk type movements are very brief but can occur many times per day.
Acute onset of bilateral facial paresis in an 8-year-old CKCS. Note the absence of menace response and decreased palpebral reflex. When the palpebral reflex is tested you can see the third eyelid is still responsive but there is very reduced movement of the eyelids. This dog has no concurrent vestibular signs.
Paroxysms of fly-catching and manic chasing behaviour in a 3-year-old CKCS. This dog had no clinical signs suggestive of gastrointestinal disease but responded completely to a hypoallergenic diet.
