Had a female we put down about 7 years ago. She made it to almost 18. Really good natured dog. Insanely
Good nose. They have a kill move/head snap thing bred in. It’s awesome. One head snap and a squirrel will fly at least 12 feet in the air over head, ass over tea kettle, back snapped and limp. They lose teeth early on, eventually go deaf and blind, the nose works to the end and they tend to stay mobile and pain free in the hips and joints. Roosevelt Rat Terriers - good damn dogs.
