Sage

Office Security

Hi. My name is Sage. I live with my mom in St. Joe. I’m a handsome rescue dog. I came from South Dakota. So did my mom. I think that’s why we get along. They say I’m an Australian Shepherd. My mom says I’m a Velcro dog.

I love to play tag with orange balls and stuffed toys and to chase the ball. I don’t like to play ‘drop it.’

I enjoy long walks with lots of sniffs and belly rubs. I go to work every day where I greet visitors at Engel Metallurgical. I’m a happy dog.
