Don't punish the growl. Trade for it.

Quick answer: Stop taking things away from the dog. Start making your approach the best part of his day. Every time you walk up to the bowl, a better treat lands in it. Get a vet to look at him first, and call a professional if he's ever broken skin.

Your dog freezes over his bowl. His eating speeds up. He gives your son a sideways look, the white of the eye showing, and a low rumble starts somewhere in his chest.

Most people do one of two things next. They yell, or they reach down, grab the bowl and say "mine." Both feel like leadership. Both make the problem worse.

What guarding actually is

Resource guarding is a dog protecting something he thinks you're about to take. Food, a chew, a stolen sock, a spot on the sofa, even you. It's normal dog behavior. It's also a problem in a house with people in it, especially small ones.

The dog isn't plotting to run the household. He's anxious about losing something. That changes the fix. You don't need to win. You need him to stop expecting a loss.

Watch for the early signs, because they come well before the bite:

• Stiffening or going still over the item
• Eating faster, or grabbing the item and carrying it off
• Hard stare, or the whites of the eyes showing
• Lip lift, then a growl, then a snap

The growl is the dog speaking plainly. He's saying, "I'm uncomfortable, back off." That's a courtesy.

Never punish the growl

Punish a growl and the dog learns the growl is dangerous. He doesn't learn the worry was wrong. The worry stays. Only the warning goes.

Now you have a dog who feels exactly the same and skips straight to the snap. People call that bite "out of nowhere." It wasn't. The dog gave notice for months and somebody told him to quit giving it.

When he growls, calmly back away. Thank him, in your own head. Then go make a plan.

See the vet first

Pain makes dogs protective. So do sore teeth, an upset stomach and arthritis. A dog who's never guarded and suddenly does deserves an exam before anything else. A senior dog especially. If that's your situation, read what an old dog actually needs from you. The vet can rule out the medical causes and tell you whether a behavior referral makes sense.

Manage the house while you train

Training takes weeks. Safety starts today.

Feed him in a separate room with the door shut, or in his crate. Pick up the bowl when he's done. Skip rawhide, bully sticks and other long-lasting chews while kids are around, or give them only behind a closed door. Put the high-value stuff, like bones, favorite toys and anything he steals, out of reach.

Then set the house rule for everyone, kids included. Nobody goes near the dog while he's eating or chewing. Nobody reaches for his bed. Small children don't read dogs well and a bite to the face is a real risk. Supervise or separate. No exceptions, no "he's fine with me."

You're serving your family first here. That means holding the line even when your kids complain that the dog is "so sweet."

The trade-up

This is the whole method, and it's boring on purpose.

Bowl. Pick a distance where he keeps eating loose and relaxed. Maybe ten feet. Walk toward him, toss a piece of chicken or cheese near the bowl, and walk away. He eats it. You leave. Do that several times a meal.

Over days, move closer. When he looks up happily as you approach, you've won that distance. Eventually you can stand beside him and drop something better into the bowl. Then you can pick up the bowl, add food and hand it back. Hands near the bowl become the sign that food is coming.

If he stiffens, you went too fast. Back up a step and stay there longer.

Toys and chews. Teach "drop it" while he's holding something dull, not something precious. Offer a treat, say the word as he lets go, and give the toy back almost every time. Taking things away forever is what makes him clamp down. Giving them back is what teaches him that letting go costs nothing. The foundation skills in Sit, Stay and Come in Fifteen Minutes a Day make this much easier.

Stolen items. Don't chase him. Chasing is a game or a threat, and either way he runs. Drop a handful of treats on the far side of the room. When he leaves the sock to eat them, calmly pick it up.

Attention and furniture. Some dogs guard a person or the couch. The fix has the same shape. Whenever a family member approaches him on the couch, treats appear. Don't grab his collar or drag him off. Lure him down with a treat and reward him for it. For a while, he may need the couch closed to him until you've built a few weeks of good feelings about visitors.

The one mistake to avoid

Don't "show him who's boss." The old alpha idea has been thrown out by most of the trainers and behaviorists worth hiring, and for good reason. Taking his food by force teaches him that guarding is justified. Some dogs will give in. Others will escalate, and you won't enjoy finding out which kind you own.

Be the calm, steady one who has the rules and keeps them. That's authority. It doesn't require a fight.

When to call a professional

Bring in help if any of these are true:

• He's ever broken skin on anyone
• He guards from children
• The growls are getting faster or he skips them
• He freezes and stares when you come near
• You're afraid of him

Ask your vet for a referral to a certified behavior consultant or a veterinary behaviorist. Ask what methods they use. If the answer is shock, choke or "dominance," keep looking. Get a price before you start. A consult costs money, and a bite costs more.

Prevent it in the next dog

If you're starting with a puppy, build this in from week one. Add a bit of food to his bowl while he's eating. Hand him a chew and give it back. Make people the source of good things. What To Do The First Seven Days With A New Puppy covers the early routine.

Leave him better than you found him. That's the standard. A dog who once guarded a bowl and now wags when you walk toward it has learned something that will protect your family for the next ten years.
