Characterization and Validation of a Canine Pruritic Model.

Preclinical Research The mechanisms mediating canine pruritus are poorly understood with few models due to limited methods for inducing pruritus in dogs. Chloroquine (CQ) is a widely used antimalarial drug that causes pruritus in humans and mice. We have developed a canine model of pruritus where CQ reliably induced pruritus in all dogs tested following intravenous administration.
