Every holiday season, homes light up with festive decorations—twinkling lights, shimmering tinsel, and beautifully hung ornaments. But for many dog owners, the joy of decorating comes with anxiety. One moment your tree is pristine; the next, a curious pup has knocked it over, scattering glass baubles and gnawing on pine-scented branches. Destructive chewing during the holidays isn’t just inconvenient—it can be dangerous. Understanding why dogs chew Christmas ornaments is the first step toward prevention. More importantly, knowing how to redirect this behavior protects both your pet and your peace of mind.
The Science Behind Canine Chewing Behavior
Dogs don’t chew ornaments out of malice. Their actions stem from instinct, curiosity, and often unmet needs. Chewing is a natural canine behavior deeply rooted in biology. Puppies explore the world through their mouths, much like human babies. Adult dogs continue chewing for stress relief, jaw health, and mental stimulation. When introduced to novel objects like shiny ornaments or dangling ribbons, a dog’s curiosity spikes. The movement, texture, and sound of these items mimic prey-like stimuli, triggering an investigative response.
Additionally, the holiday season brings changes that can increase anxiety in dogs: altered routines, loud noises, unfamiliar guests, and new scents. Stress-induced chewing is common. A dog may resort to destructive behaviors as a coping mechanism when overwhelmed. In some cases, boredom plays a major role—especially if the dog is left alone near tempting decorations without adequate enrichment.
“Dogs chew not because they’re ‘bad,’ but because their environment doesn’t meet their physical or emotional needs.” — Dr. Karen Overall, Veterinary Behaviorist
Why Ornaments Are Particularly Tempting
Not all household items attract equal attention from dogs. Ornaments are uniquely appealing due to several factors:
- Visual Movement: Hanging ornaments sway with air currents, mimicking small animals in motion—a powerful trigger for predatory instincts.
- Reflective Surfaces: Shiny baubles reflect light unpredictably, catching a dog’s eye and stimulating chase behavior.
- Novelty: Introduced suddenly into the home, ornaments represent new “toys” to investigate.
- Scent: Some ornaments carry traces of food, glue, or artificial fragrances that appeal to a dog’s sensitive nose.
- Texture: Plastic, wood, or fabric ornaments offer varied chewing sensations, satisfying oral exploration.
Even non-edible items can pose serious risks. Broken glass ornaments can cause mouth or digestive tract injuries. Tinsel and string can lead to linear foreign body obstructions—a life-threatening condition requiring surgery. Electrical cords from lights present electrocution hazards, especially for puppies.
Step-by-Step Guide to Prevent Ornament Chewing
Stopping destructive behavior requires more than scolding or confinement. Effective prevention combines management, training, and environmental enrichment. Follow this timeline to safeguard your home and help your dog adapt.
- Week 1: Assess and Secure
Survey your home for high-risk zones. Identify where your dog spends most of their time and place fragile decorations out of reach. Consider using a baby gate to block off rooms with trees or fragile decor. Use cord protectors on light strands and secure the tree base to a wall with invisible brackets. - Week 2: Introduce Positive Alternatives
Provide durable chew toys that satisfy your dog’s oral needs. Rotate toys weekly to maintain interest. Freeze stuffed Kongs with peanut butter (xylitol-free) or bone broth for long-lasting engagement. Place these near the tree area so your dog associates the space with positive rewards. - Week 3: Train Boundary Commands
Teach “leave it” and “stay” using positive reinforcement. Start in low-distraction environments, then gradually practice near the tree. Reward your dog generously for ignoring ornaments. Never punish after the fact—this creates fear, not understanding. - Week 4: Simulate Real Conditions
With supervision, allow controlled access to the decorated room. Monitor closely and intervene at the first sign of interest in off-limits items. Redirect to appropriate toys immediately. Over time, your dog will learn acceptable boundaries. - Ongoing: Maintain Consistency
Holiday habits formed this year set the tone for future seasons. Continue reinforcing rules, rotating toys, and managing access when unsupervised.
Do’s and Don’ts of Dog-Safe Holiday Decorating
| Do | Don’t |
|---|---|
| Use unbreakable plastic or fabric ornaments, especially below 3-foot height | Hang fragile glass or metal baubles within jumping distance |
| Secure the tree stand and use fishing line to anchor top branches | Rely solely on scent deterrents (many are ineffective or unsafe) |
| Provide supervised access only when you're home | Leave your dog unsupervised in the room with the tree |
| Use bitter-tasting sprays (pet-safe) on tree trunks and lower branches | Apply human-grade essential oils—many are toxic to dogs |
| Offer chew toys specifically during holiday gatherings | Scold or shout when chewing occurs—this can increase anxiety |
Real Example: How Max the Border Collie Learned Tree Boundaries
Max, a two-year-old Border Collie in Colorado, had a reputation for toppling Christmas trees. His owners loved traditions but dreaded December. After Max chewed through a power cord and required emergency vet care, they consulted a certified dog trainer. The solution wasn’t punishment—it was structure.
The family installed a freestanding pet gate around the living room, allowing Max visual access without full entry. They placed a cozy bed inside the barrier with a view of the tree and filled it with frozen treat toys. Each evening, they practiced “leave it” near the tree, rewarding Max with high-value chicken bits for compliance. Within ten days, Max stopped approaching the tree altogether. By Christmas morning, he lounged nearby, indifferent to the ornaments, focused instead on his stuffed marrow bone.
Their success came from consistency, not perfection. On busy days, they simply closed the gate. Over time, Max learned the tree was off-limits—not through fear, but through clear expectations and better alternatives.
Expert-Approved Strategies to Reduce Destructive Chewing
Prevention works best when aligned with a dog’s natural needs. Veterinarians and animal behaviorists emphasize proactive measures over reactive corrections.
- Increase Daily Exercise: A tired dog is less likely to engage in destructive behavior. Aim for at least 30–60 minutes of active play or walks daily, more for high-energy breeds.
- Mental Enrichment: Puzzle feeders, snuffle mats, and hide-and-seek games tire the mind as much as the body. Rotate activities to prevent habituation.
- Safe Chewing Zones: Designate a specific area with approved chews. Dogs thrive on routine—when they know where and what to chew, they’re less tempted elsewhere.
- Avoid Reinforcing Attention-Seeking: If your dog chews an ornament to get a reaction, calmly remove them without engaging. Reward quiet, independent behavior instead.
“Management is 80% of behavior modification. You can’t train a dog to ignore temptation they’re constantly exposed to.” — Jean Donaldson, Founder of The Academy for Dog Trainers

Frequently Asked Questions
Can I use vinegar or lemon spray to keep my dog away from the tree?
While citrus scents are unpleasant to dogs, homemade sprays like vinegar or lemon juice aren’t consistently effective and may damage ornaments or flooring. Instead, use commercially available pet-safe bitter sprays designed for chewing deterrence. Always test on a small area first and avoid spraying near food or water bowls.
My dog only chews ornaments when I’m not home. What should I do?
This suggests separation-related anxiety or boredom. Never leave your dog unsupervised near the tree until they’ve proven reliable. Crating or confining them to a safe room with toys and background noise (like a radio) can help. Consider hiring a dog walker during long absences to break up the day.
Are certain breeds more prone to chewing decorations?
Yes. High-drive breeds like Border Collies, Australian Shepherds, and Terriers are more likely to explore with their mouths due to strong herding or hunting instincts. Puppies of any breed are also at higher risk due to teething and curiosity. However, any dog can develop destructive habits if under-stimulated or anxious.
Conclusion: A Safer, Happier Holiday Starts Today
Your dog’s urge to chew Christmas ornaments isn’t defiance—it’s communication. It signals unmet needs for activity, clarity, or comfort. By addressing the root causes and implementing smart, compassionate strategies, you can enjoy the holidays without constant vigilance. Prevention isn’t about restricting your dog; it’s about enriching their experience so they don’t feel compelled to seek stimulation in dangerous places.
This season, commit to a plan that protects your pet, preserves your traditions, and strengthens your bond. Start early, stay consistent, and remember: every dog can learn. With patience and the right tools, you’ll create memories that sparkle—without the shattered glass.
