Resource guarding

A dog protecting something valuable: food, a chew, a toy, a spot, sometimes a person. It is not dominance and it is not defiance. It is anxiety that the thing is about to disappear.

Repeatedly taking food away proves the fear correct. The dog learns that a human near the bowl means loss, and guards harder. The goal is the opposite belief: a human approaching means MORE, not less.

· Work at a distance where they keep eating calmly and do not stiffen. That distance is your starting point.
· Walk past, toss something better than what they have, walk away. Do not approach the bowl. Do not linger.
· Repeat until your approach makes them look up hopefully rather than stiffen.
· Close the distance over weeks, driven by their body language rather than your schedule.
· For objects, teach a formal trade: offer something better, they drop, they get BOTH back sometimes. The occasional return is what stops trading feeling like a trick.
· Prevent rehearsal meanwhile: feed behind a closed door, pick up contested items when they are not there, manage rather than test.

· Do not take food or objects away to 'prove' you can
· Do not put your hand in the bowl while they eat
· Do not punish a growl — see reading your dog. It is the warning you want to keep.
· Do not free-feed in a multi-dog house
· Do not let children near a guarding dog, at any stage, for any reason

Guarding directed at children, guarding a person, any bite that broke skin, or escalation despite work. That is a veterinary behaviorist or a qualified behavior consultant, not a group class — and in the meantime, management rather than training: closed doors, no contested items, no testing.

· Jean Donaldson, 'Mine! A Practical Guide to Resource Guarding in Dogs' — the standard protocol most consultants use
· American Veterinary Society of Animal Behavior (avsab.org) — position statement on dominance theory
· International Association of Animal Behavior Consultants (iaabc.org)
· American College of Veterinary Behaviorists (dacvb.org) — for cases involving a bite

Better treats and closed doors. There is nothing to buy that fixes this.
