Description of our model

The strain was created by R. W. Dawley in 1925, from a hooded male hybrid of unknown origin and an albino female (probably Wistar), and was crossed with the female’s progeny for 7 generations.

The SPRAGUE DAWLEY® rat is an albino outbred rat with an elongated head and a tail that is longer than its body.

A fast growing rat, it is docile and easy to handle.
