“I just don’t like her”

Why Doesn’t My Dog Like Some Dogs?

Often I meet dogs who show some degree of aggression or reactivity towards other dogs - but it doesn’t happen with every dog. Sometimes it seems random.

But is it really?

When There’s a Clear Pattern

In some cases, you can see a theme. Maybe your dog reacts more to:

  • Fluffy dogs

  • Flat-faced breeds

  • Certain sizes or body types

It’s like a little doggy prejudice. At least then, there’s a pattern we can work with.

When It Feels Random

Other times, it’s harder to explain. Why do some dogs seem fine with most, but then blow up at one random stranger dog in the park?

Think of it like this: have you ever met someone at a party, been introduced to a mutual friend, and just… not liked them?

  • Maybe you couldn’t put your finger on why.

  • Maybe it was the look on their face.

  • Maybe they said something that rubbed you the wrong way.

  • Maybe it was me and you’re about to unsubscribe… 😅


But the point is: sometimes we just don’t click with everyone. And neither do our dogs.

Possible Reasons Your Dog Dislikes Certain Dogs

There’s always some reason, even if it’s not obvious to us. For example:

  • The other dog might be too energetic and coming off as “rude.”

  • Both dogs may carry themselves in a dominant way, and neither wants to give in.

  • Or maybe your dog got the doggy finger from a passing poodle once and never forgot that b*tch’s face.


Whatever the reason, we can’t expect our dogs to like every single dog they meet.

What You Can Do

Even if we can’t control your dog’s “friend list,” we can:

  • Train them to listen under distraction.

  • Learn to read body language so you can step in early.

  • Build better communication through training together.


The benefits? A stronger bond, clearer communication, quicker learning, and a tired (a.k.a. calmer) dog. Win, win, win.
