You adopted a dog three months ago. Lately, whenever you walk into the kitchen, he eats faster and faster, hunched over the bowl, tail completely still. Or you have a five-month-old puppy who growled for the first time yesterday when you went to take his bone. Or you have a four-year-old, and the dog goes rigid every time your child walks past while he is eating, and it has frightened you. All of this has a name: resource guarding. The old advice, "take his bowl away so he gets used to it", makes it worse. The plan that works gets him, within a few weeks, glad to see you coming anywhere near his food.
Why dogs guard food and other things
Because he is a dog. An animal who gives up his food to anyone who walks over does not survive, and dogs come with that program built in: strong in some, barely visible in others. It is not a flaw in his character and it has nothing to do with "dominance". It is the fear of losing something he cares about a great deal. And it behaves like any fear: it grows when you prove it right and shrinks when you prove it wrong.
What dogs guard, from most to least common: food in the bowl, bones and chews, stolen things (socks, tissues, the remote), places (the sofa, the bed, his own bed), sometimes a person in the house, and more rarely water or a corner of the garden. A dog can guard a bone and be completely relaxed at his bowl. He decides what matters to him.
The signs come in steps. The lower down you catch them, the easier your job:
- he eats faster as you approach, gulping;
- he freezes with his head in the bowl and stops chewing;
- he puts his body between you and the object, or turns his back with the bone in his mouth;
- he follows you with his eyes only, head still, the whites of his eyes showing;
- a low growl without lifting his head;
- lips lifted, or snapping at the air;
- a bite.
The dog who "bit out of nowhere at the bowl" has been through every step above, usually for months, without anyone noticing. Or he skipped them because the lower steps were punished.
Where it comes from, in the order we tend to see it
Things taken from his mouth. Every time someone took something from him or lifted his bowl, he learnt that a person coming close means losing something. After ten experiences like that, he is on guard the moment he sees you coming.
Competition for food. A puppy raised with eight littermates at one bowl, a street dog, a shelter dog in tightly packed kennels. They learnt that food disappears unless you defend it.
Punished growling. He growled and was told off or smacked. He learnt that growling only gets him into trouble, so next time he goes straight to his teeth.
"Testing". The person who puts a hand in the bowl to get him used to it, or takes the bone to see what he does. Every test confirms to the dog that he was right to guard.
How much the thing means to him. A dog who has never guarded anything may guard a marrow bone or a baby rabbit he found in the grass. Same dog; it is just the first time he has had something that good in his mouth.
Several dogs. At a shared bowl, one of them always loses and learns not to.
Hunger and pain. A dog who is always hungry (too little food or poor food, worms, absorption problems) guards harder. A dog in pain guards the place where he lies because being touched hurts.
What does not work, even when it seems to
Taking the bowl away mid-meal so he understands it is yours. He understands the opposite: when the person comes, the food goes. Some dogs back off, frightened, and it looks as if it worked. Others guard harder by the fifth go. Either way you end up with a dog who tenses the moment you come near his dinner.
A hand in the bowl to get him used to it. Same mechanism. Your hand can go to the bowl, but only to add something, never to take.
Punishing the growl. The growl is the only warning he gives before his teeth. Punish it and it disappears, leaving you with no warning at all. The dogs who "bite without growling" we meet almost exclusively in homes where growling was punished.
Chasing him for the stolen thing. To the dog it is the best game in the house. On top of that he learns to swallow what he has grabbed quickly so it cannot be taken, and a swallowed sock often means surgery.
Fingers in his mouth to get the bone. Works right up until the day it does not, and that day ends in A&E.
Cornering him. The dog has taken the bone under the table and the person crawls in after him. With no way out, the dog has one option left and he uses it.
The trick swap. You show him a treat and say "give", he drops the object, and you take it and walk off without handing over the treat. It works once. The second time he drops nothing, and fair enough.
Having your child stroke him while he eats, so he gets used to children. A child approaching a dog who is eating is one of the situations in which children are most often bitten, at home, by the family dog. Children stay away from a dog who is eating. No exceptions.
The plan, step by step
The point of the plan is to change what your approach means. Right now it means "here comes someone to take my stuff". You want it to mean "here comes someone bringing something". Until that changes, nobody goes near the dog when he has something he cares about. How you arrange the house is half the treatment, from day one.
1. Set the house up from day one
He eats alone, in a room with the door shut or behind a baby gate. Pick the bowl up once he has finished and walked away from it. Bones and chews are for the crate or pen only, door closed, and you collect them after he has wandered off by himself. Socks, tissues and remotes disappear from his level. Children do not go near him while he eats or chews, and if you cannot guarantee that, he eats in a locked room. If he has stolen something dangerous, trade it straight away for something really good (see step 5). If it is something harmless, let him have it. The fight is not worth it.
2. The map
For two weeks, write down what he guards, from whom, and at what distance the first signs appear, such as gulping or freezing. The distance at which he is still relaxed is your starting distance. For some dogs it is three metres, for others it is the kitchen door.
3. The approach that brings something
He is eating from his bowl. You appear at the safe distance, toss towards him something much better than what he has (a piece of meat, some cheese) and leave straight away without stopping. Do this a few times every meal, day after day. You know it is working when he lifts his head happily as you appear, instead of eating faster. Only then do you come a step closer. Within two or three weeks you reach the bowl, and then your hand comes in and drops something tasty inside without touching anything else. Bones follow the same route but more slowly, because a bone matters far more to him.
4. "Give", taught by trading
Start in play, with things he does not care much about. He has some ordinary toy in his mouth; you show him a treat and he lets go. Say "give", hand him the treat, praise him cheerfully and give the toy back. Almost every time the toy goes back to him; just now and then you keep it and give him something else instead. He learns that "give" means "you get something good and usually get your thing back too". Over the following weeks, work up one at a time to things he cares about more.
Separately, practise "leave it" to head off stealing. Put a treat on the floor and cover it with your palm. When he looks at you instead of nosing under your hand, he gets something good from your other hand and some praise. Then try it without the palm. Then outdoors, with whatever he finds on the ground.
5. Stolen things
Do not chase him. Go into another room and open the fridge noisily. Or toss a few treats two or three metres away from him in the opposite direction, and while he goes after them, calmly pick up the object. If it is something dangerous (medication, chicken bones, a sock), offer him the best thing in the house right now, no bargaining. You pick the training back up tomorrow.
6. With a puppy, from the first week
With a puppy the plan is the same and takes about a week. The hand that comes near the bowl always adds something better. Toy trades daily, in play. The bone only ever leaves by trade. Children practise the bowl exercise only with an adult beside them, tossing the treat from a distance. A puppy raised like this guards nothing, or so little that nobody notices.
The first week
| Day |
What you do |
| 1 |
He eats alone behind a door. Bones in the pen only. Everything stealable put away. The children learn the rule. |
| 2–3 |
Note distances and what he guards. Vet appointment if it started suddenly or he eats more than before. |
| 4–5 |
First "approach that brings" at the bowl, from the safe distance, 3–4 times a meal. "Give" with an ordinary toy, 5 trades. |
| 6–7 |
Same exercises. If he lifts his head happily when he sees you, one step closer. If not, stay there another week. |
When it is a medical problem
Resource guarding is not an illness. Even so, your own vet should rule out a few things if:
- it started suddenly in a dog who never guarded anything;
- he eats much more or more greedily than before, drinks more or has lost weight despite eating (hormonal or digestive problems, worms, or a treatment that boosts appetite);
- he guards his resting place and flinches when you touch him (joint or back pain);
- he startles and growls when you approach from the side or behind (failing sight or hearing);
- he is old, has started guarding new things and seems disoriented (brain ageing).
Tell your vet exactly what he guards and since when. A dog guarding his bowl because worms are leaving him hungry needs tests, not training.
When to call in a professional
- he has bitten hard enough to break the skin, anyone, in any guarding situation;
- there are small children at home and he guards food or places;
- he guards a person (growls at your partner when they come near you on the sofa) or whole areas of the house;
- you have two dogs who fight over the bowl or bones;
- you cannot find any distance at which he stays relaxed;
- you have followed the plan consistently for four weeks and the signs have not eased.
Resource guarding responds very well when caught early and very poorly after months of "testing". A professional will start from your map and usually change two things: who goes near the dog while he eats (for a while, nobody) and what approaching him brings.
A behaviour that appears suddenly or changes for no apparent reason can have a medical cause. For full details, consult your dog's own veterinarian.
