This animal has bilateral congenital exotropic strabismus. Here the defect appears to be in the orbital bone structure although without a high resolution ultrasound examination investigation of extraocular muscle anatomy is very difficult. Strabismus, though common in children, is very rare in dogs. The Bichon shownin this second picture developed a unilateral strabismus after injury, a far more common cause than the congenital problem seenin the puppy.
