VIDEO 1: Neurological diseases of the Cavalier King Charles Spaniel (1)

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.

VIDEO 4: Neurological diseases of the Cavalier King Charles Spaniel (4)

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.
