How to Stop Resource Guarding in a Great Dane
Updated · How we write our guides
Short answer
Address resource guarding in your Great Dane by combining management with gradual desensitization and positive reinforcement, such as teaching 'Leave it' and practicing controlled exchanges. Because of their large size, patient consistency and building positive associations prevent confrontation and safely resolve anxieties.
If there has been a bite, the reactions are intense, or things are getting worse, see your vet first to rule out pain, then work with a certified behavior consultant or veterinary behaviorist.
Resource guarding in Great Danes requires patient, careful intervention due to their large size and powerful build—even friendly dogs can cause injury when guarding. Great Danes are naturally gentle and dependable, making them excellent candidates for positive-reinforcement training to overcome this behavior. Their moderate trainability (3/5) means consistency and clear communication are essential. Resource guarding typically stems from anxiety rather than aggression, and because Great Danes are patient by nature, they respond well to gradual desensitization combined with reward-based protocols. This guide focuses on safely resolving guarding of food, toys, and spaces through management, training, and creating positive associations—all without confrontation or punishment.
How to do it
Step-by-step
Tick off each step as you practice it — your progress is saved on this device.
Step 1: Identify and manage trigger situations
Observe when your Great Dane guards most (mealtimes, specific toys, furniture, doorways) and temporarily remove the trigger to prevent rehearsal of guarding. For example, hand-feed meals or pick up toys immediately after play rather than leaving them accessible. Management buys you training time without stress on your dog.
Step 2: Teach 'Leave it' as a foundation behavior
Use positive reinforcement to teach a reliable 'Leave it' command with low-value items first (treats, toys). Reward your Dane generously when he releases on cue. Given their moderate trainability, practice daily in short 5-minute sessions during their typical 60-minute daily exercise window.
Step 3: Build positive food associations with your approach
Randomly approach your Dane's empty bowl and toss high-value treats into it; never remove his bowl during meals. This teaches him that your approach predicts good things. Repeat this for 2–3 weeks before progressing, and do it when he's calm, not during peak guarding moments.
Step 4: Practice controlled resource exchanges
Once he associates your approach with rewards, offer a treat while he eats, then allow him to continue. Gradually work up to briefly touching his bowl, always rewarding generously with treats better than his meal. For a 150+ lb Great Dane, never create confrontation—reward cooperation heavily.
Step 5: Desensitize to spatial intrusions gradually
Walk closer to his eating area over successive sessions, pausing at a distance where he remains calm. Reward calm behavior from several feet away, then one foot away, then beside him. Your Dane's friendly temperament will support this, but patience is key—progress at his pace.
Step 6: Maintain long-term management and consistency
Even after improvement, continue hand-feeding portions of meals and rewarding calm behavior around resources. Avoid situations where multiple dogs or people approach simultaneously, and keep children trained on respecting his space during meals. Consistency prevents regression in a dog of his size.
For the Great Dane
Pro tips
- Never hand-feed from an open palm early on—use a closed fist or treat dispenser to protect your fingers, especially given your Dane's size. Accidental nips during training setups can set progress back significantly.
- Leverage his friendly temperament by having different family members reward calm behavior around resources on different days. Great Danes bond strongly, and variety in rewards keeps training engaging and prevents him from 'guarding' you specifically.
- Combine training with his natural leaning behavior—when he leans against you calmly during a training session near his resources, reward it heavily. This channels his gentle nature into a positive, submissive posture that naturally discourages guarding.

Frequently asked questions
My Great Dane growls when I approach his food bowl—is this dangerous and should I punish it?
Growling is communication, not a sign he's 'dominant,' and punishment will only increase his anxiety and bite risk. Never punish guarding behavior. Instead, create distance and begin management and positive-association work immediately. Given his size and power, preventing escalation through reward-based training is essential for everyone's safety.
How long will it take to resolve resource guarding?
This varies by severity and consistency, but most Great Danes show measurable improvement in 4–8 weeks with daily practice. Some cases take 3–6 months. Your Dane's friendly, patient temperament works in your favor, but his moderate trainability (3/5) means steady repetition is crucial—skip days and progress stalls.
Should I use his 60 minutes of daily exercise to train during this process?
Light training (5–10 minutes) works well during or after exercise when he's calm and focused, but don't exhaust him beforehand. Great Danes have moderate energy (3/5), so brief, positive training sessions fit naturally into his routine. A calm, exercised Dane learns better than an anxious, understimulated one.
My Great Dane guards toys but not food—can I use the same approach?
Yes, the same principles apply. Start by removing his trigger toys, teach 'Leave it,' then gradually reshape his response through positive associations and controlled exchanges. Toy guarding often resolves faster than food guarding because toys carry less survival value, so progress may be quicker.
When should I get professional help for my Great Dane's resource guarding?
Get help if your Great Dane stiffens, growls, snaps, or bites when people come near food, toys, or resting spots, if guarding is directed at children, or if it's getting worse. Start with a vet visit to rule out pain, then work with a certified behavior consultant (IAABC or CCPDT) or a veterinary behaviorist. In the meantime, prevent confrontations by feeding separately and never reaching for or taking items from a guarding dog.
