Why Is My Dog Guarding Me From My Other Dog?

You’re petting one dog, and your other dog rushes over — wedging between you, blocking your hand, or growling to push them away. It feels possessive, even personal, like they don’t want to share you.

It’s a stressful moment for any dog parent.

Most people’s first instinct is to scold, reassure, or separate. But those reactions, while understandable, often make things worse.

Punishing adds stress. Comforting can accidentally reward the behavior. Constant separation prevents dogs from learning that calm coexistence is possible.

Before labeling your dog as jealous or protective, it helps to understand what’s really happening.

Dogs don’t guard because they’re being dramatic. They do it because of emotion: insecurity, tension, or confusion. Once you understand why, you can teach your dogs that sharing you is safe and predictable.

If you’ve seen tension or scuffles between your dogs before, our Aggression & Reactivity Training in Chicago can help rebuild trust safely.

It can feel like jealousy, but it’s not that simple.

Dogs are emotional learners. When they guard a person, they’re reacting to how they feel, not plotting to control you. Sometimes that feeling is insecurity (“Will I lose this attention?”). Sometimes it’s tension with the other dog. And sometimes it’s overstimulation (too much excitement in a tight space).

The underlying emotion can fall into one or more of these categories:

1. Insecurity or true resource guarding

The dog worries about losing access to something valuable (you). They might stiffen, lean into you, or side-eye the other dog. It’s not dominance. It’s uncertainty.

2. Overstimulation or emotional spillover

Dogs who get worked up easily during greetings or play may redirect that energy into blocking or barking. The goal isn’t to protect you; it’s to release tension.

3. Social conflict between the dogs

If your dogs already have friction, your attention can become the spark. You’re not the resource — you’re just the trigger zone.

4. Discomfort or pain

Sometimes guarding behavior appears when a dog doesn’t want to be jostled or touched. What looks like “claiming” can actually be “I’m sore, please give me space.”

5. Lack of impulse control

For puppies and adolescents, barging in or pushing between you and another dog is often just excitement and poor manners, not an emotional issue.

For younger pups, our Puppy Training Classes in Chicago focus on patience, impulse control, and calm confidence from the start.

What NOT to do when this happens

When your dog guards you from another, it’s natural to want to step in fast — but most human instincts actually make the behavior worse.

You might raise your voice, separate the dogs, or comfort the one who’s growling, hoping it helps. BUT - each of those reactions teaches your dog the opposite of what you want them to learn.

1. Don’t Punish or Scold

Yelling, clapping, or grabbing collars adds more stress to an already tense moment.

To your dog, it confirms that the other dog’s presence = bad things happen. That makes them feel even more protective the next time it happens.

2. Don’t Comfort or “Reassure” During Guarding

It’s easy to say, “It’s okay, buddy,” or reach to pet them mid-growl, but that attention can reinforce the behavior.

Your dog learns that guarding you is a reliable way to get your focus and affection.

3. Don’t Force Sharing or Togetherness

Trying to “make them get along” on the couch or during petting time can push things too far.

Dogs need structure and safety, not pressure. If they’re already tense, forced closeness can quickly turn into a fight.

4. Don’t Separate Every Time Without a Plan

Immediate safety comes firs! But constant separation teaches your dog that guarding works.

Instead, pair brief separations with calm training moments, so they can practice staying relaxed around each other without losing access to you forever.

The Key Idea:

Every reaction teaches something. When we respond with calm structure, instead of panic or pity, dogs learn that they don’t have to manage the situation themselves.

What to Do Instead

1. Establish Predictable Routines

Dogs relax when they know what to expect. Keep affection consistent, with clear turns and boundaries, so neither dog feels uncertain about when their attention is coming.

2. Practice Calm Sharing

Reward both dogs for staying relaxed when you engage with one. Over time, they learn that calm behavior (and not guarding) makes good things happen.

3. Manage Hot Spots

If tension happens in specific contexts (like on the couch or at bedtime), create separate relaxation zones temporarily while you rebuild calm behavior.

4. Reinforce Emotional Balance

Enrichment, sniff walks, decompression, and training games help burn off tension that can spill into guarding. The calmer the mind, the calmer the relationship.

When to Call in Help

If there’s growling, snapping, or a fight history, it’s time to bring in professional guidance. A certified trainer can identify which emotions are driving the behavior — insecurity, frustration, or conflict — and build a plan that keeps everyone safe.
