Is Your Dog "Reactive"... Or Are They Hurting? Let's Talk About Pain & Behaviour
I see it all the time in my training sessions. A client comes to me because their dog is lunging, barking, or "acting out" on walks. They’ve tried the treats, they’ve tried the corrections, and they’re frustrated.
But here’s the truth that doesn't get talked about enough: You cannot train away physical pain.
When a dog is 'reactive,' they aren't choosing to be a 'problem'. Often, they’re just trying to protect themselves because they feel vulnerable. If your hips ached or your back was stiff, you’d probably be a bit "snappy" too if someone rushed into your personal space!
What To Look For: Subtle Signs of Discomfort
It's not always a dramatic limp. Look for these subtle cues:
•Changes in Gait: Is their stride shorter? Are they shifting weight? Is there a slight stiffness when getting up?
•Reluctance to Move: Hesitation to jump into the car, go up stairs, or play as vigorously.
•Changes in Posture: A tucked tail, hunched back, or head held lower than usual.
•Sensitivity to Touch: Pulling away when petted in certain areas.
•Self-Licking/Chewing: Obsessive licking of a specific paw or body part.
•Changes in Appetite or Sleep: These can be indicators of overall systemic discomfort.
•New Onset Reactivity: If your previously calm dog suddenly becomes reactive, pain should be high on your list of suspects!
•Guarding Behaviour: Protecting certain body parts or resources more intensely than before.
My professional advice? If your dog’s behaviour has changed suddenly, or if your training has hit a total brick wall, stop training and start checking. A vet visits to rule out silent pain (like arthritis, GI issues, or dental pain) is the most "pro-dog" thing you can do.
I’m here to help you with the behaviour side, but I want to make sure we’re helping the whole dog, mind and body.
