When a dog shows aggression to protect his food, it can be a serious issue. Not only is there the danger of other dogs or humans in the house being bitten, but over time it can lead to the dog becoming possessive over everything.
In a dog pack, the alpha dogs always eat first after a successful hunt, and then the other dogs get what’s left according to their pack position.
For an alpha dog, showing food aggression is a form of dominance, but for dogs with a lower pack position, it can be a sign of anxiety or fearfulness. Remember, in the wild, dogs never know where or when their next meal will be, so it’s very instinctual for them to gobble up whatever food there is whenever they have it — and to protect it from anything that approaches.
Also assess your dog’s overall confidence and behavior. If he is naturally a dominant dog, then you will need to assert yourself as the Pack Leader in a calm and assertive way. On the other hand, if he is timid or fearful, you will need to build up his confidence and teach him that his food is safe with humans around.
For severe cases, start off by consulting a professional until you can get the dog down to a moderate level.
If the source of your dog’s aggression is fear or anxiety over when the next meal is coming, then be sure that you are feeding your dog at the same times every single day.
Dogs have a very good internal clock, and with consistency, they quickly learn how to tell when it’s time to get up, time to go for a walk, or time for the people to come home. Mealtime should be no different. Be regular in feeding to take away the anxiety.
Before you even begin to prepare your dog’s food, make her sit or lie down and stay, preferably just outside of the room you feed her in. Train her to stay even after you’ve set the bowl down and, once the bowl is down, stand close to it as you release her from the stay and she begins eating, at which point you can then move away.
Always feed your dog after the walk, never before. This fulfills his instinct to hunt for food, so he’ll feel like he’s earned it when you come home. Also, exercising a dog after he eats can be dangerous, even leading to life-threatening conditions like bloat.
Pack leaders eat first
Remember, when a wild pack has a successful hunt, the alpha dogs eat first, before everyone else, and it should be no different in a human/dog pack.
Never feed your dog before or while the humans are eating. Humans eat first and then, when they’re finished, the dogs eat. This will reinforce your status as the Pack Leader.
“Win” the bowl
Food aggression can actually be made worse if you back away from the bowl, because that’s what your dog wants. For every time that you do walk away when the dog is showing food aggression, the dog “wins.” The reward is the food and this just reinforces the aggression.
Of course, you don’t want to come in aggressively yourself, especially with moderate to severe food aggression, because that is a good way to get bitten. However, you can recondition the dog until she learns that she wins when she lets you come near her while eating.
Here are some of the techniques you can use:
Hand feeding: Start your dog’s meal by giving him food by hand, and use your hands to put the food in the bowl, which will give it your scent. The goal is to get your dog used to eating while your hands are around his face, and to have no aggressive reaction if you stick your hands in or near the bowl while he’s eating.
Treat tossing: Drop your dog’s favorite treats into the bowl while she’s eating so she’ll learn that people approaching the bowl is a good thing and not a threat. You can also put treats into the bowl when you walk near it and she’s not eating. This reinforces the connection in your dog’s mind that people near her bowl is good.
“Trade-Up”: When your dog is eating their regular food, approach them with something better, like meat or a special treat. The goal here is to get your dog to stop eating their food to take the treat from you. This teaches your dog several things. One is that no one is going to steal his food if he looks away from it. The other is that removing his attention from his food when people come around leads to a reward.
The key, is to be calm, assertive, and consistent.
