I get followed by a dog and 3 cats. My other 3 the girls stay in our bedroom. They follow me when I go to the master bathroom lol so I am ALWAYS followed.
And when my daughter was a toddler she followed me to.
I tell my dog where I'm going in the same tone and words so she gets used to them. "Going for the mail"; she's okay. "Be right back", she's okay. But if I head downstairs where the garage and car are without saying anything, you know I'm going to 'hear' it.
Me: Don't jump off the couch you're old, I'll be back in a second
My dog: *already jumping* my body is as young and free as a baby gazelle, I am the wind
