Although we humans have good days and bad days, sometimes for no discernible reason, I tend to assume that a dog's perspective doesn't change much from one day to the next. I tend to expect that a dog will respond in the same way to training or potentially scary things every single day.
Shyla is a dog who makes it very obvious that she has a complex inner world that isn't always the same. Some days, she surprises me with her confidence. Other days, she surprises me with her fearfulness when I can't see anything to be afraid of.
Today was one of those days. I tend to show photos of her when she looks confident and happy. I think you'll agree with me that neither of those adjectives describes her in the next photo.
I also wondered about whether Shyla might be smelling scary wildlife. I later discovered that a bobcat had spent ten minutes in front of a nearby trail camera.
I also know that a mountain lion has been in our neck of the woods very recently although I don't know whether he's still in the area. Perhaps Shyla smelled him? She is, without a doubt, scared of the scent of mountain lions.
Why shouldn't dogs have similar inner things that cause them to act differently from usual? Perhaps Shyla had a migraine. Oh man - I hope not!
She did have fun on our morning hike, especially when she was playing in the snow or galloping at full speed. I captured a photo close to the end of our hike after she'd been playing in the forest that shows the "normal" Shyla.
