Quick Overview
- A dog’s jumping ability is directly tied to shoulder height and breed drive, not just size. A standard four-foot fence is not enough for most medium to large breeds.
- In practice, chain link remains the most common fence choice among dog owners
- Solid fencing like wood or vinyl tends to work best for reactive or anxious dogs, since blocking the view of passersby reduces the barking and pacing that an open fence can trigger.
- Digging is one of the most common ways dogs get out, and it usually needs a buried barrier, not just a taller fence, to actually stop.
- The weakest point of almost any dog fence is the gate. A standard gravity latch is easy for a determined or heavy dog to bump open.
- Electronic or invisible fencing carries a meaningfully higher escape rate than a physical fence and does nothing to keep other animals or people out of the yard.
Why Dog Fencing Needs Its Own Approach
A fence built purely for privacy or property lines does not automatically work as a dog fence. Containing a dog safely means thinking about height relative to what that specific dog can actually clear, gaps a dog could squeeze through or dig under, and how the fence affects the dog’s behavior day to day, not just whether it looks good from the street.
How High Does a Fence Actually Need to Be?
Jumping ability comes down to shoulder height and motivation, and the rule of thumb used in canine behavior circles is that a healthy, motivated dog can clear roughly one to three times its own shoulder height. That range matters, since a fence that comfortably contains a calm dog on a normal day might not hold the same dog if something outside genuinely excites or startles it.
As a general guide: small breeds typically need a fence around 3 to 4 feet, medium breeds closer to 4 to 5 feet, and large breeds generally need 5 to 6 feet. High-drive working breeds, huskies, border collies, and similar athletic dogs, can often clear a standard 6-foot fence entirely, which usually means height alone is not enough and some kind of anti-climb addition is worth considering.
Keep in mind that Ottawa’s fence bylaw caps rear and side yard fences at 2.13 metres, or about 7 feet, and front yard fences at just 1 metre. That front yard limit is worth factoring in if a dog will ever have access to that part of the property, since it is not tall enough to contain most medium or large dogs on its own.
Choosing a Material With Your Dog’s Personality in Mind
Wood. A solid, board-on-board wood fence blocks the view completely, which genuinely helps dogs that bark, pace, or get worked up at every passing person or car. Vertical boards also give a dog nothing to grip if it tries to climb. The tradeoff is that wood can be chewed through by a determined dog and needs the usual upkeep to avoid rot at the base of the posts.
Vinyl. Vinyl offers the same full visual block as wood, without the chewing or rot concerns, since the panels are smooth and solid. The one thing worth knowing for this climate is that lower-grade vinyl can become brittle in extreme cold, which matters if a large dog is likely to jump against the fence with any real force in winter. Higher quality vinyl fences built with proper impact modifiers hold up far better here.
Aluminum. Aluminum is strong, low maintenance, and impossible to chew through, but its open picket design means a dog can see everything happening outside the yard at all times. For a calm, confident dog, that is not a problem. For a reactive or territorial dog, it can actually make barking and fence-running worse rather than better. Standard picket spacing can also be wide enough for small dogs to squeeze through, which is usually solved by adding tighter-spaced pickets along the bottom section.
Chain link. Chain link is the most budget-friendly option for a large area, but the diamond mesh essentially gives an athletic dog a built-in ladder to climb. It also offers no privacy, which can contribute to barrier frustration in reactive dogs. If a chain link fence is the right fit for your situation, a bottom tension wire or rail is worth adding, since a loose bottom edge is one of the easiest places for a dog to push under and escape.

Stopping a Dog From Digging Out
Digging is one of the more common ways dogs get loose, and taller fencing does nothing to solve it. The most effective fix is what is sometimes called an L-footer or predator apron: a section of heavy wire mesh attached to the bottom of the fence, bent outward at a right angle, and pinned flat along the ground. Grass grows over it within a season, and when a dog tries to dig right at the fence line, its paws hit solid wire instead of open dirt. For fences with a chronic, determined digger behind them, burying the fence material itself a foot or two underground, or pouring a concrete footer along the fence line, is a more permanent but more labor-intensive solution.
Preventing Climbing and Jumping
For dogs that use the fence itself to climb rather than clearing it in one jump, a couple of add-ons make a real difference. A coyote roller is a free-spinning bar installed along the top of the fence. When a dog hooks its paws over the top to pull itself up, the roller spins and gives it nothing to grip, so it drops back down safely instead of getting over. An angled extension, leaning inward at the top of the fence, works on a similar principle by making the final stretch physically harder to clear.
The Gate Is Usually the Weak Point
A fence can be perfectly built and still fail at the gate. Standard gravity latches can be bumped open by a dog jumping against the gate, or simply fail to catch properly over time. A magnetic, self-latching hardware upgrade closes and locks automatically every time, without relying on gravity or a perfect swing to engage. It is also worth checking the gap at the bottom of the gate itself. A gap of more than three or four inches is enough for a small dog to squeeze under, and it is an easy detail to miss since the rest of the fence looks secure.
Winter Changes the Math Too
A six-foot fence is not really six feet once a few feet of packed snow builds up against it. It is worth thinking through how snow accumulation affects effective fence height in your specific yard, particularly near a shed, deck, or corner where drifting tends to pile up.
Why the Foundation Matters as Much as the Fence Itself
A fence built to contain a strong, athletic dog needs real structural stability, and that starts below the ground, not above it. Ottawa’s soil is prone to frost heave, where freezing ground grips a shallow post and gradually pushes it upward over successive winters. A fence that has heaved even a couple of inches can leave a gap at the bottom rail wide enough for a dog to walk straight through. Posts need to sit below the local frost line, roughly 3.5 to 4 feet in this region, to avoid that problem entirely.
A Word on Invisible or Electronic Fencing
Electronic containment is often marketed as a simple, attractive alternative to a physical fence, but it comes with real tradeoffs worth knowing before relying on it. Dogs contained by electronic fencing have a meaningfully higher recorded escape rate than dogs behind a physical fence, largely because a strong enough motivation, chasing a squirrel or reacting to another animal, can override the anticipation of a static correction in the moment. It also only works in one direction. It may keep a dog in, but it does nothing to keep other animals, or people, out of the yard. A properly built physical fence remains the more reliable option for both containment and overall safety.
Common Mistakes Worth Avoiding
Choosing a fence based on looks alone. An elegant, open-picket fence can genuinely work against a reactive or anxious dog by giving it a constant view of everything happening outside the yard.
Underestimating what a dog can actually climb or jump. A six-foot chain link fence looks secure, but the mesh itself can act as a climbing aid for an athletic dog in a way a solid panel never would.
Focusing on height while ignoring the bottom of the fence. A small gap at the base of the fence or gate is often the actual escape route, not the top.
Not accounting for snow buildup. A fence that is plenty tall in October can be considerably shorter, functionally, by February.
What This Means for Your Yard
The right fence for a dog depends on that dog’s size, temperament, and specific habits as much as it does on the yard itself. If your dog is a climber, a digger, or gets worked up easily by what is happening outside the fence line, it is worth building those specific concerns into the design from the start rather than adding fixes after the fact.

FAQs
How tall should my fence be to keep my dog in the yard?
It depends on the dog. As a general guide, small breeds need about 3 to 4 feet, medium breeds 4 to 5 feet, and large or high-drive breeds 5 to 6 feet or more, sometimes with anti-climb additions.
What’s the best fence material for a dog that barks at everything?
Solid wood or vinyl tends to work best, since blocking the dog’s view of the street reduces the visual triggers that lead to barking and pacing.
How do I stop my dog from digging under the fence?
A buried wire mesh barrier, sometimes called an L-footer, bent outward along the base of the fence is one of the most effective and least labor-intensive solutions.
Can a dog really climb a chain link fence?
Yes. The diamond mesh pattern gives many dogs enough foothold to climb, especially athletic or motivated breeds.
Is an invisible fence a good alternative to a physical fence?
Generally not recommended as a primary containment method. Electronic fencing has a higher recorded escape rate than physical fencing and does not protect a dog from outside threats entering the yard.
Does Ottawa’s fence height bylaw affect what I can build for my dog?
Yes. Rear and side yards allow up to 2.13 metres, but front yards are capped at just 1 metre, which is not tall enough to contain most medium or large dogs.
Summary
Keeping a dog safely contained takes more than picking a tall fence and calling it done. The right height depends on the specific dog, the right material depends on its temperament, and the details that actually prevent escapes, buried barriers against digging, anti-climb additions, secure gate hardware, and a properly set foundation below the frost line, matter just as much as the fence itself. Building with your dog’s specific habits in mind from the start is far more effective than trying to patch problems after an escape.
