Also called · food aggression · guarding the bowl · bites when touched while eating
What it looks like
- Freezes when you come near while eating
- Growls or shows teeth
- Guards even the empty bowl after eating
Why it happens
A leftover from competing for food
It is thought to be a remnant of getting food according to rank, and of competing over food with animals they are not close to. A strongly possessive dog may guard even the empty bowl after the meal.
It is not because "I rank too low"
The idea that a dog assigns social rank to human family members is now viewed sceptically. Taking food away to "establish rank" is not only poorly supported — it can make things worse.
Owner intervention escalates the conflict
In multi-dog households the higher-ranking animal eats first as a rule. If the owner intervenes in a way that breaks that rule, rank becomes unstable and aggression can increase.
What to do
Do not touch them while they eat
The first job is removing the trigger. Training that involves putting a hand in the bowl or taking food away makes the problem bigger.
Feed them somewhere quiet and separate
Put the bowl away from other animals and from foot traffic, so there is less reason to guard in the first place.
Be careful using treats in training
Using highly palatable treats can be risky with a dog that guards food. Some dogs value play or being stroked more than food, so work out what this dog actually wants first.
Work with a professional
If biting has already happened, do not try to fix it alone. Get counselling from a behaviour specialist.
Watch out for
In dogs showing aggression toward their owners, a high-protein diet without added tryptophan significantly increased aggression. See the aggression entry for detail. (DeNapoli et al., JAVMA 217, 2000)
See a vet if
Has already bitten a person
Bites without any warning signal
Common questions
Not recommended. From the dog’s side it builds up experience of food being taken, which strengthens guarding. Reducing the situations that call for guarding is safer.
