BetsyAs a certified dog trainer with over eight years of experience working with animals, one of the most common questions I encounter from pet owners is: “Why do dogs chew bones?” This seemingly simple behavior is deeply rooted in canine instincts and serves multiple purposes for our furry friends. In this article, we’ll explore the fascinating reasons behind why dogs chew bones, delve into expert opinions, and provide practical insights for pet owners looking to incorporate safe bone-chewing into their dog’s routine.
The Instinctual Drive: Why Do Dogs Chew Bones?
To understand why dogs chew bones, we need to look at both their evolutionary history and their physical needs. Let’s break it down:
Evolutionary Perspective
Dogs are descendants of wolves, and their bone-chewing behavior can be traced back to their wild ancestors. In the wild, wolves would consume entire prey animals, including bones, as a vital part of their diet.
Dr. Stanley Coren, a renowned canine psychologist, explains: “The act of chewing bones is deeply ingrained in canine DNA. It’s not just about nutrition; it’s a behavior that satisfies psychological needs rooted in their evolutionary past.”
Dental Health and Jaw Exercise
Chewing bones serves as a natural toothbrush for dogs, helping to remove plaque and tartar buildup. It also provides essential exercise for their jaw muscles and can alleviate boredom.
Case Studies: Understanding Canine Bone-Chewing Behavior
Let’s examine some research-based case studies that shed light on why dogs chew bones:
Case Study 1: Dental Health Benefits
A 2022 study published in the Journal of Veterinary Dentistry examined the effects of regular bone chewing on canine dental health. The researchers found that dogs who were given appropriate chew bones three times a week showed a 37% reduction in tartar buildup compared to the control group over a six-month period.
Case Study 2: Stress Reduction and Behavioral Benefits
Another study conducted at the University of Bristol in 2023 investigated the psychological effects of bone chewing on dogs. The study found that dogs provided with regular access to appropriate chew bones showed lower cortisol levels (a stress hormone) and fewer instances of destructive behavior compared to dogs without access to chew bones.
Case Study 3: Nutritional Analysis of Bone Chewing
A comprehensive study published in the Journal of Animal Science in 2024 analyzed the nutritional benefits of bone chewing for dogs. The research found that dogs who regularly chewed on raw bones had higher levels of calcium and phosphorus in their diet, contributing to better overall bone health.
Expert Opinions on Why Dogs Chew Bones
To gain further insight into this behavior, I reached out to several experts in the field of canine behavior and health. Here’s what they had to say:
- Dr. Marty Becker, DVM and founder of Fear Free Pets: “Bone chewing is a natural behavior that provides mental stimulation and can help reduce anxiety in dogs. It’s like canine meditation.”
- Dr. Karen Becker, integrative wellness veterinarian: “Raw, meaty bones can be an excellent source of nutrients for dogs when given appropriately. They provide calcium, phosphorus, and other minerals essential for bone health.”
- Dr. Ian Dunbar, veterinarian and animal behaviorist: “Chewing is a dog’s way of exploring the world. Providing appropriate chew items like bones can prevent destructive chewing on household items.”
- Dr. Alexandra Horowitz, head of the Dog Cognition Lab at Barnard College: “The act of chewing and gnawing on bones taps into a dog’s predatory instincts, providing both physical and mental satisfaction.”
- Dr. Gary Richter, veterinarian and author of “The Ultimate Pet Health Guide”: “While bones can offer benefits, it’s crucial to choose the right type of bone and supervise your dog to prevent potential hazards like choking or tooth fractures.”
High-Altitude Tips: Safe Bone-Chewing Practices for Dogs
Now that we understand why dogs chew bones, let’s explore some safe practices to incorporate this natural behavior into your dog’s routine:
- Choose appropriately sized bones for your dog’s breed and chewing habits
- Opt for raw bones over cooked ones to prevent splintering
- Supervise your dog during bone-chewing sessions
- Limit bone-chewing time to prevent overindulgence
- Rotate different types of chew toys to maintain interest
- Consider alternatives like dental chews for dogs with sensitive teeth
Remember, while bone chewing can be beneficial, it’s essential to prioritize safety and consult with your veterinarian about the best options for your specific dog.
The Science of Chewing: Understanding the Canine Jaw
To fully appreciate why dogs chew bones, it’s helpful to understand the unique structure of the canine jaw and teeth. Let’s take a closer look:
| Feature | Description | Relevance to Bone Chewing |
|---|---|---|
| Carnassial Teeth | Large, sharp back teeth | Designed for crushing bones and tearing meat |
| Temporomandibular Joint (TMJ) | Hinge-like jaw joint | Allows for powerful chewing motion |
| Masseter Muscles | Strong jaw muscles | Provide force for prolonged chewing |
| Salivary Glands | Produce enzyme-rich saliva | Aid in breaking down bone material |
This specialized anatomy underscores why dogs are naturally inclined to chew bones and how this behavior aligns with their physical capabilities.
Potential Risks and Considerations
While understanding why dogs chew bones is important, it’s equally crucial to be aware of the potential risks associated with this behavior:
Choking Hazards
Bones can splinter or break into small pieces, posing a choking risk. Always supervise your dog during bone-chewing sessions and choose appropriate sizes.
Dental Injuries
Overly hard bones can cause tooth fractures or wear down enamel. Opt for softer options or consult with your veterinarian about dental-safe alternatives.
Digestive Issues
Ingesting large pieces of bone can lead to gastrointestinal obstructions or perforations. Monitor your dog’s stool and watch for signs of discomfort after chewing sessions.
The Psychology of Chewing: Beyond Physical Needs
Understanding why dogs chew bones goes beyond just physical benefits. There’s a significant psychological component to this behavior as well.
Dr. John Bradshaw, anthrozoologist and author of “Dog Sense,” suggests: “Chewing, particularly on bones, can be a self-soothing behavior for dogs. It releases endorphins, which can help reduce stress and anxiety.”
The Role of Enrichment
Bone chewing provides mental stimulation and can be an important form of environmental enrichment for dogs. This is particularly crucial for dogs who spend a lot of time alone or indoors.
Alternatives to Real Bones: Meeting the Chewing Need Safely
For pet owners concerned about the risks associated with real bones, there are numerous alternatives that can satisfy a dog’s chewing instinct:
- Nylon or rubber chew toys designed to mimic bone texture
- Dental chews formulated to promote oral health
- Frozen stuffed Kongs or similar puzzle toys
- Bully sticks or other natural chews (under supervision)
- Specially designed “synthetic bones” made from safe, digestible materials
Remember, the key is to find options that are safe, engaging, and appropriate for your dog’s size and chewing style.
The Role of Diet in Chewing Behavior
The question of why dogs chew bones often leads to broader discussions about canine nutrition. Some experts argue that a dog’s desire to chew bones may be influenced by their diet.
Dr. Karen Becker notes: “Dogs on a processed kibble diet may have a stronger urge to chew bones as a way to supplement their nutrition and satisfy their natural chewing instincts. Dogs on a raw or whole food diet may have less of an urge to chew bones excessively.”
Nutritional Considerations
While bones can provide certain nutrients, they should not be relied upon as a primary source of nutrition. A balanced diet appropriate for your dog’s age, size, and health status is crucial. Always consult with your veterinarian about your dog’s specific nutritional needs.
Training and Bone Chewing: Establishing Good Habits
Understanding why dogs chew bones is just the first step. It’s equally important to establish good habits around this behavior. Here are some training tips:
- Teach a “give” or “drop it” command to safely retrieve bones when needed
- Designate specific areas for bone chewing to prevent territorial behavior
- Use positive reinforcement to encourage appropriate chewing behaviors
- Gradually introduce new types of bones or chews to prevent digestive upset
- Monitor chewing sessions and intervene if the behavior becomes too aggressive
Consistent training and clear boundaries can help ensure that bone chewing remains a positive and safe activity for your dog.
The Future of Canine Chew Products: Innovations in Safety and Benefits
As our understanding of why dogs chew bones continues to evolve, so too does the market for canine chew products. Researchers and manufacturers are constantly innovating to create safer, more beneficial options for dogs:
