Dog Reactivity: 3 Things to Do.

Over the years, I’ve worked with many dogs - especially reactive dogs, as well as puppies settling into their new homes, rescue dogs adjusting to a new life, and adolescent dogs suddenly “forgetting everything” they once knew.
One of the most important things I’ve learned (and something I really want you to understand, too) is this:
Dogs are contextual learners.
This means their behaviour changes depending on the situation they’re in.
A few examples you might relate to:
Your dog is friendly at daycare, but reactive on the leash
Your puppy was calm at the breeder’s home… and now feels like a little tornado
Your dog listens at home, but not outside
This isn’t your dog being difficult - it’s your dog responding to a different environment.

Many dogs go through noticeable changes around adolescence (6–18 months). You might see:
More pulling
Over-excitement
Selective listening
New fears
This is completely normal, but it can feel confusing if you’re not expecting it.
On top of that, factors like past experiences, recovery from surgery, genetics, and early life exposure all play a role in how your dog behaves.
So what can you start doing today?
Keep it simple 👇
|
For example: If your dog sees another dog and doesn’t react → say “Yes” and reward. If they choose to look at you → reward.
Small moments like this build big change.
|
For example: If your dog jumps on people or gets over-excited when saying hello → stay further away where they can stay calm.
At that distance:
reward calm behaviour (like standing nicely or sitting);
then gradually move closer over time.
If you’re too close and they’re already jumping or barking → they can’t learn.
Distance = learning space.

Every dog is an individual. The more we understand their context, the easier training becomes - and the better your relationship will feel.
I've helped many people, and if you want to understand your dog's context and improve the relationship, I am here for you.
