I’ve worked with Bullmastiffs my whole life, and I’ve seen the tension that can build at mealtimes when big, food-driven dogs live with curious children. Resource guarding — when a dog growls, stiffens, or protects food or toys — is frightening for families and often misunderstood. The good news is that, with patience, predictable management and positive conditioning, you can teach both dogs and children to share space safely around food without confrontation or punishment.

What resource guarding really is (and what it isn’t)

Resource guarding is a natural, evolutionary behavior: dogs have learned to protect items that are valuable to them. But guarding becomes a household problem when it creates safety risks for children. It’s important to remember that guarding is a communication tool — not defiance. Responding with punishment or confrontation usually makes the behavior worse by increasing anxiety.

First steps: safety and management (before you start training)

Before any behavior-change work, make the environment predictable and safe. Management is the foundation that prevents incidents while you re-train the dog’s emotional response to children near food.

  • Separate mealtimes: Feed dogs on a routine away from play areas. Use a separate room, kitchen corner or behind a baby gate where the children are not allowed during feeding.
  • Crates and designated "place": For many Bullmastiffs, a crate, mat or elevated bed can become a calm, accepted feeding location. If your dog tolerates a crate positively, feeding in the crate (door open if the dog prefers) is a safe pattern.
  • Supervision and rules for kids: Children must never approach a dog while it’s eating. Teach them to wait until the dog finishes and goes to its crate or place, then say a cue (like "OK") before approaching to collect bowls.
  • Use barriers: Baby gates, exercise pens, or even closed doors are simple tools that stop accidental interactions while you change behavior. You’re not “isolating” the dog — you’re preventing learning of bad outcomes and protecting everyone.
  • Change emotions, not just behavior: counterconditioning and desensitization

    Our goal is to change how a dog feels when a child is near food — from anxiety or threat to “good things happen.” This requires two linked strategies: counterconditioning (pairing the child’s approach with positive outcomes) and desensitization (gradually increasing the child’s proximity).

    Here’s an approach I use, adapted for a home with children:

  • Start at a distance where the dog is relaxed. Have a calm adult or older child toss high-value treats (small cooked chicken bits, or a soft commercial treat like Zuke’s Mini Naturals) to the dog from that distance. The child should not make sudden movements or try to take the bowl — they simply toss treats.
  • Repeat until the dog looks to the child expectantly rather than tensely. Then, over days or weeks, the child takes a small step closer and repeats the same pattern. Progress only when the dog remains relaxed.
  • Always end sessions on a good note. Short, frequent sessions (5–10 minutes, 1–2 times daily) are more effective than long, stressful ones.
  • Train reliable cues that keep everyone safe

    Teaching children and dogs predictable cues reduces confusion and anxiety. A few that I find most useful:

  • “Place” or “Bed” — teach the dog to go to a mat or bed and stay while people move around. Reinforce with treats and longer stays over time. This gives kids and caregivers a clear signal: when the dog’s on place, it’s safe to move about.
  • “Leave it” and “Drop” — these are essential. Start with low-value items and reward generously when the dog complies. Use high-value trade-up rewards (a better treat for a lesser item) so the dog learns giving up is rewarding.
  • Polite bowl approach — you can teach the dog that you may approach the food bowl while it eats by associating your hand near the bowl with better food. Start by tossing a higher-value treat into the bowl from a distance, then gradually touch the bowl and drop something more valuable into it. This rebuilds trust if done carefully and only when the dog is relaxed.
  • Teach children what to do (and what not to do)

    Kids are part of the solution. They need clear, age-appropriate rules and supervised practice:

  • Never reach over the dog’s head for food or toys.
  • Always ask an adult before interacting with the dog during mealtime.
  • Practice calm movements and quiet voices around dogs that are eating.
  • Use role-play: have children practice “approach and toss” with a stuffed toy or while an adult feeds the dog treats from a distance.
  • Using food to build trust: hand-feeding and trade-up games

    Hand-feeding is a powerful tool when done safely. Feeding small portions by hand at times when the dog is relaxed — not during tense guarding episodes — communicates that people are the source of food and good things. Start with soft, small bits and stop if the dog shows stress.

    Trade-up games teach the dog that giving up food or toys yields something better. For example:

  • Offer a low-value item. Present a very tasty treat (cheese, cooked turkey) and say “drop” — when the dog releases, reward and praise.
  • Gradually practice with higher-value items until the dog reliably trades.
  • When the problem is more than training

    Some cases of guarding are rooted in anxiety or medical issues (poor body condition, pain, cognitive decline). If a dog’s guarding is severe, unpredictable, or getting worse, consult your veterinarian first to rule out health causes. Then work with a qualified force-free professional — a certified applied animal behaviorist or force-free trainer experienced with large breeds and children.

    Practical kit and product suggestions

    There are simple products that help implement management and training:

  • Baby gates (e.g., Evenflo or Carlson brands) to separate spaces.
  • Elevated mats or durable beds (K&H Pet Products bolster beds) for “place” training.
  • Small, high-value treats for training: real cooked meat, Zuke’s Minis, or single-ingredient dehydrated treats.
  • Long lines or head halters for extra control during training sessions with proximity work (use carefully and with professional guidance).
  • Patience is essential. Bullmastiffs are smart, loyal dogs, and they respond well to calm, consistent teaching. When we change the way the dog feels about children near their food — pairing approach with better outcomes, giving clear signals, and managing risk — we build long-term safety without confrontation or punishment. Keep interactions predictable, reward calm behavior, and involve your children in gentle, supervised training. Over time, mealtimes will become a peaceful routine where everyone knows the rules and feels secure.
