Border Collies are widely considered the most intelligent dog breed — and they’re also one of the healthiest from a dental standpoint. Their well-proportioned skull, full scissors bite, and active chewing habits give them natural advantages over many modern breeds. But their high energy and chewing drive also create specific risks that attentive owners should understand.
Border Collie Dental Anatomy
Border Collies are medium-sized herding dogs (30–55 lbs) with a long, proportional muzzle. Their jaw structure allows all 42 adult teeth adequate space, with a standard scissors bite. Unlike brachycephalic breeds, they don’t struggle with overcrowding or retained baby teeth as common breed-specific concerns.
Their dental risk profile is moderate-to-low — similar to other athletic herding breeds like German Shepherds and Australian Shepherds. With consistent preventive care, Border Collies can maintain excellent dental health well into their teens.
Common Dental Problems in Border Collies
Periodontal Disease
The most prevalent dental condition in Border Collies is standard periodontal disease — plaque hardens to tartar, causes gum inflammation, and progresses to bone loss around tooth roots. Without any home care, a Border Collie will typically show notable tartar and mild gingivitis by age four to five.
Border Collies’ active lifestyle and natural chewing helps slow tartar accumulation somewhat — mechanical chewing provides plaque removal that sedentary house dogs don’t benefit from as much. But no amount of natural chewing replaces brushing. Read more about the progression: Dog Dental Disease: Causes, Stages & Treatment.
Tooth Fractures from Compulsive Chewing
Border Collies are compulsive, intense chewers — especially dogs without adequate mental and physical stimulation. A bored, under-stimulated Border Collie will chew through hard objects that less driven dogs would ignore. This makes tooth fractures a meaningful risk in this breed.
The upper carnassial (4th premolar) is the most commonly fractured tooth in all medium-to-large dogs. In Border Collies with strong chewing drives, this tooth is at particular risk from: fence biting (a stress behavior in confined Border Collies), catching hard objects, or finding and chewing rocks.
Any tooth that appears grey, brown, or discolored — or any tooth with a visible chip or crack — should be evaluated with dental X-rays. Tooth fractures that expose the pulp lead to abscess within months if untreated.
Fence and Object Biting Wear
Highly anxious or under-stimulated Border Collies may develop repetitive fence-biting or object-mouthing behaviors. This causes abnormal wear patterns — particularly on the incisor teeth — that can eventually expose dentin or pulp. If your Border Collie’s incisors look noticeably shorter or worn flat, consult your vet about dental evaluation and behavioral enrichment.
Border Collie Dental Care Routine
Brushing
Daily brushing is the most effective preventive tool. Border Collies are highly trainable and typically accept tooth brushing well when introduced systematically — their intelligence means they learn the routine quickly and can even come to expect it as part of their daily schedule.
Use a medium toothbrush and enzymatic dog toothpaste. Focus on the outer surfaces of premolars and molars. Full guide: How to Brush Your Dog’s Teeth the Right Way.
Safe Chew Management
Given Border Collies’ high chewing drive, providing safe, appropriate outlets is especially important — both for dental health and behavioral management. VOHC-approved dental chews, rubber Kong-style toys, and medium-density nylon chews are appropriate. Avoid antlers, weight-bearing bones, and very hard items.
Critically: address the underlying cause if your Border Collie is chewing destructively or compulsively. A Border Collie that chews because of boredom, anxiety, or insufficient exercise will cause dental damage regardless of what chew items you provide. Adequate daily exercise (often 2+ hours for active Border Collies), mental stimulation, and appropriate training address the root issue. See our chew guide: Best Dental Chews for Dogs.
Monthly Checks
Given Border Collies’ tendency to find and chew unusual objects, monthly at-home tooth checks are particularly worthwhile. Lift the lip and check both sides — look for chips, cracks, and discoloration that might indicate a previously missed fracture. See the checklist: Signs Your Dog Needs a Professional Teeth Cleaning.
Professional Dental Cleanings for Border Collies
Most Border Collies benefit from professional dental cleaning under anesthesia every 12 to 18 months. Dogs with more active chewing habits or heavier tartar accumulation may need it annually. Border Collies have no breed-specific anesthetic concerns — they’re healthy, well-proportioned dogs that tolerate standard anesthesia well.

Frequently Asked Questions About Border Collie Teeth
Do Border Collies have good teeth?
Relatively yes — Border Collies have well-proportioned jaws with adequate space for their 42 teeth, which reduces overcrowding and helps natural self-cleaning through saliva flow. They’re significantly better placed than toy breeds and brachycephalic breeds from a structural standpoint. However, their high chewing drive creates a meaningful fracture risk that other low-key breeds don’t face as strongly.
Why do Border Collies chew so much?
Chewing in Border Collies is partly instinctive (herding dogs use their mouths extensively) and partly a response to their exceptional energy and intelligence needs. When those needs aren’t met — through adequate exercise, mental stimulation, and training — compulsive chewing behaviors can develop. A well-exercised, mentally enriched Border Collie typically has a calmer, more controlled chewing habit.
How often should I brush a Border Collie’s teeth?
Daily brushing is ideal. At minimum four times per week provides meaningful protection. Border Collies are typically excellent students for tooth brushing training — their intelligence and routine-following tendencies work in your favor.
Can a Border Collie break a tooth on a frisbee or ball?
Hard plastic frisbees and hard rubber balls can occasionally cause tooth fractures if caught with force at the right angle — particularly the canine teeth. Use soft rubber or fabric frisbees and flexible rubber fetch balls to reduce this risk. Any tooth that looks chipped, discolored, or appears shorter than the corresponding tooth on the other side should be evaluated.
