From Dog

Polyuria (pollakiuria) in dogs is defined as the excessive production of urine in excess of 50 ml/kg/day.

Polyuria is normally associated with polydipsia, which is usually concurrent and compensatory, except in diabetes insipidus, where polydipsia starts first.

Many dogs with polyuria have concomitant hyposthenuria.
