The Rat Terrier wasn’t a recognized breed by the AKC until 2013. It was more a type with a recognized, descriptive name. They were the most common type of dog in the US until the 1950’s, when small farms were replaced with industrial operations. They were popular for this exact reason; pest control.
I’ve taken these two ratting at the breeders hobby farm. I have a third one (tri color piebald) that we got from a rescue, but haven’t had a chance to bring her. The two pictured are acktchually half brothers (different side/dad) but are way different sizes, with one at the very smallest and the other at the very largest. They always have a blast ratting, and it’s pretty wild seeing them do what they’re supposed to do. You can tell that they’re naturally good at it.
