As professional pet sitters, we walk into homes full of personality—some furry, some feisty, and all a little different from one another. One behavior that can take even experienced sitters by surprise is guarding—when a dog becomes possessive over food, toys, or even people. Understanding the signs of resource and human guarding can help you stay safe, build trust with pets, and communicate better with your clients.
You know the look. That “I dare you to touch my squeaky toy” glare a dog gives right before clamping their jaws like they’re guarding the Crown Jewels. Or the way a pup suddenly becomes your shadow, growling at the cat for daring to breathe near you. Welcome to the fascinating (and occasionally dramatic) world of resource and human guarding—where dogs lay claim to snacks, toys, and yes, even you.
As pet sitters, we sometimes play the role of caregiver, referee, and unintentional chew toy inspector—all in the same afternoon. Let’s unpack what guarding is, why it happens, and how to handle it like the calm, treat-equipped pet pro you are.
What Is Resource Guarding?
Resource guarding is a behavior where a dog becomes defensive or aggressive to protect something they value. That “something” could be:
- Food or treats
- A favorite toy
- A bed or resting spot
- A chew bone (this is always a “bone of contention” with dogs, especially in a pack)
- Even stolen items (yes, even socks count!)
Guarding can manifest through growling, stiffening, showing teeth, snapping, or outright lunging. It’s often rooted in fear or insecurity—dogs who feel their prized possession might be taken away react to prevent that loss.
What Is Human Guarding?
This one can feel even more personal: human guarding is when a dog becomes possessive over a person—and that person might be you during a pet sit! Dogs might bark, growl, or snap at others (people or animals) who get too close to their “chosen” human.
You might see this when:
- You’re giving affection and another pet walks up
- You’re chatting with a neighbor and the dog gets in between
- You try to leave the room, and the dog blocks your way
- Friends come over (if you offer in-your-home boarding)
Why It Matters for Pet Sitters
As sitters, we drop into the dog’s world—we’re the new face, the temporary caregiver, and sometimes the unexpected “rival.” Guarding behavior can pop up during transitions, especially if the dog is stressed, uncertain, or adjusting to a different routine.
Some pet parents might not even know their dog guards, or they may underestimate how the dog will behave in their absence.
Some dogs only show guarding behaviors when their humans are away, and routines are disrupted. That means even well-behaved pups can surprise you with possessive quirks you didn’t see coming. Recognizing the early signs helps keep everyone safe and sets you up for success.
Signs to Watch For
- Stiff body language or hovering over a toy or bowl
- Growling or baring teeth when approached near food or high-value items
- Blocking you from moving or getting near certain areas
- Showing jealousy when you interact with other animals or people
- Becoming overly attached and anxious when you try to leave (this is also prevalent with dogs who suffer separation anxiety)
WHAT YOU CAN DO
- Prevent the Problem
Don’t try to take items from a dog unless absolutely necessary. Trade up with a treat or distract with another toy. Avoid hovering during meals or when they’re chewing something high value. - Use Neutral Zones
Feed dogs in a quiet, separate area. If there are multiple pets, give each their own space for meals and chews. - Watch Your Body Language
Move calmly, speak softly, and avoid leaning over a dog who seems stiff or tense. - Establish Boundaries Early
Don’t allow clingy or possessive behavior to escalate. Gently discourage dogs from following you room to room or sleeping on your lap if it’s leading to guarding. - Communicate With Pet Parents
If you notice guarding behavior, document it clearly and kindly. Pet parents may be unaware, and your observations could help them work with a trainer. - Safety First
Never put yourself at risk. If a dog’s guarding behavior escalates or feels dangerous, remove yourself from the situation and notify the owner immediately.
Pet Pro Tip of the Day: If a dog is guarding a dirty sock like it’s made of gold, don’t play tug-of-war—unless you’re trying to win the World’s Most Awkward Game of Keep Away. Instead, offer a high value treat and say, “Wanna trade?” Dogs love a good bargain when snacks are involved.
Guarding is normal, but that doesn’t mean it’s harmless. With a little awareness and a sprinkle of patience, you can navigate these behaviors confidently and keep your pet sits smooth, safe, and stress-free.
You’ve got the leash, the treats, and now the know-how—go forth and guard your own sanity out there!
