It's a reflex when we see someone we love nervous or distressed! “It's Okay!” we exclaim!
Unfortunately, we're giving them a completely DIFFERENT message!
We don't say “It's Okay” or “Don't Worry” when a dog feels happy or relaxed. We use our human language of “It's Okay” to reassure the dog we love. Unfortunately, they don't understand our words, just the associations they make with them. Use the things they already have positive associations with. Smelly soft treats, a firm rub, and a slow deep “Gooooood dog” go a lot further.
