Some days, my dog is cool as a cucumber. We walk past the usual triggers—bikes, runners, even that one dog that always stares—and she barely reacts. I start thinking, “Wow, maybe we’ve turned a corner!” Then, the next day, she’s on edge from the moment we step outside. Every noise, every movement sets her off. What changed?

I used to think it was training regression, or maybe I did something wrong. But the more I observe her (and, honestly, myself), the more I realize: energy is everything. Just like us, our dogs have good days and bad days, and a lot of that comes down to how much energy they’re carrying.

The Build-Up Effect

Reactivity isn’t just about what happens in the moment—it’s cumulative. If my German Shepherd, who’s nearly four now, has had a stressful day (or even a few little stressors in a row), that tension doesn’t just disappear overnight. A dog barking through the door, a loud garbage truck, or even a windy day where everything moves unpredictably—it all adds up. And if she doesn’t get a chance to shake it off properly, it carries into the next day.

Energy In, Energy Out

On days when she’s extra reactive, I ask myself: Did she get enough movement? Did she get too much? Mental stimulation? Did something overstimulate her? Some days, we get the balance just right—physical exercise, sniffy walks, brain games, calm moments. Other days, she gets too amped up (even in a “fun” way) and can’t fully wind down. And when that happens, it’s like walking around with a ticking time bomb of pent-up energy.

What Helps?

• Sniffing & Foraging – A long sniffari walk or scattering kibble in the grass helps burn energy without making her more amped up.
• Shorter, Controlled Walks – If she’s already on edge, I skip the long route and do a shorter, calmer one instead.
• Mental Work – Puzzle toys, nose work, even just practicing cues like “touch” or “find it” at home can work wonders.
• Calm Connection – On the rough days, I let go of the pressure to “fix” things and just focus on being with her. Sometimes, a good cuddle or a few deep breaths together helps reset us both.

If you ever feel like your dog is backsliding, take a step back and think about what’s been going on beyond the obvious. Their energy isn’t just about the moment—it’s about everything leading up to it. And honestly? That’s a lesson I’ve had to learn for myself, too.
