"Oh they're service dogs. That's so sad, they can't interact with anyone..."
Yes, that was said to my hoomans this morning. Twice. And my mum who is usually very polite, couldn't help herself but respond to them!
It is true, as a working dog (not a service dog, as in Australia that term applies to police and other emergency service, as well as defence force dogs,) we're not supposed to interact with other animals or hoomans when we're working. We have to stay focused on our hoomans so that we can alert to changes that we detect and task.
But when we're out of coat, we do interact with others. It's called a healthy work life balance. We have plenty of downtime to just be puppers.
