Resource Guarding: What you need to know!Posted on September 23, 2019September 9, 2025

Resource guarding is showing up more and more in companion dogs, especially in young, otherwise healthy dogs. It can be scary and stressful for owners — sometimes it even strains the relationship with their dog.

The good news? Resource guarding is one of the easiest behaviours to prevent and often one of the easiest to treat.

What Is Resource Guarding?

Resource guarding is when a dog becomes protective of something they find valuable. It isn’t always about food. Dogs may guard:

• Food or water
• Bowls, KONGs, or treat-dispensing toys
• Toys and bones
• Space or furniture
• People
• Pretty much anything your dog sees as important

Warning Signs to Watch For

Before aggression happens, most dogs give clear warning signs, including:

• Eating faster when someone approaches
• Body stiffening
• Lip lifting or showing teeth
• Low, deep growling
• Side-eye glances toward the “threat”

These signals are your dog’s way of saying, “I’m not comfortable — back off.”

Why Does It Happen?

There are several causes of resource guarding: genetics, poor early socialisation, or even health issues. But one of the most common reasons is outdated advice given to puppy owners, such as:

• “Pat the dog while they’re eating.”
• “Put your hand in their bowl.”
• “Take away their food while they eat, then give it back.”

The intention behind this advice is to “teach” tolerance. The reality? It does the opposite. Each time you interfere, you give your dog evidence that their food or toy isn’t safe around you. Dogs are incredibly tolerant — until one day, after months or even years of building up “evidence,” they snap.

When owners say a bite came “out of the blue,” it usually didn’t. The dog was showing discomfort all along, but those subtle signals were missed.

How to Prevent Resource Guarding

The key is to change the “evidence” you’re giving your dog. Instead of proving you’re a risk to their resources, show them you add value.

Here’s how:

• When your dog is eating, approach with something even more valuable (like chicken or cheese).
• Toss the treat near their bowl and walk away.
• Repeat so your dog learns: “When people come near my stuff, good things happen.”

Over time, your dog may even pause eating, look at you, or offer a sit; their way of saying, “Hi friend, do you have something for me?” That’s when you know you’re on the right track.

Multiple-Dog Households

If you have more than one dog, don’t feed them side by side. Even if you’ve “never had an issue,” you’re adding unnecessary stress.

Think of it like siblings. If one finishes their plate of chips first, you can bet they’ll eye the other’s. Same with dogs; competition makes guarding more likely.

Feed dogs separately, give high-value items in controlled situations, and prevent problems before they start. It’s always easier to avoid guarding behaviours than to rehab a dog who’s learned that everything is at risk of being taken away.
