Designing a Side Gate for Dogs: Height, Gaps and Secure Latches
Key Takeaways: A dog-safe side gate needs to prevent escape over, under and through the gate while remaining securely latched.
Choose height according to the dog's size, jumping and climbing behaviour rather than appearance alone.
Keep batten, post and bottom gaps too small for the dog to squeeze through or become trapped.
Pay particular attention to uneven ground, digging areas and objects that reduce effective gate height.
Use reliable latching hardware and consider a self-closing mechanism where gates are frequently used.
Select aluminium, timber, tubular or solid designs around both the dog and everyday household access.
An attractive side gate can work perfectly for people, bins and garden access but still be unsuitable for a dog. A side gate for dogs needs to prevent four possible escape routes: over the gate, underneath it, through openings within or beside it, and through the gate if the latch can be pushed or is accidentally left unsecured.
The best design therefore depends not only on your home and pathway, but also on your dog's size, behaviour, jumping ability and previous escape habits.
How Should You Design a Side Gate for Dogs to Stop Them Getting Over, Under or Through It?
A dog-safe gate needs to work as a complete containment system. Height alone will not help if the dog can squeeze beside the hinge post, dig underneath the gate or push open an unreliable latch.
How High Should a Side Gate Be for a Dog?
The right side gate height depends on the individual dog rather than simply its shoulder height.
Dog size and build: Larger dogs generally require a greater physical barrier.
Jumping ability: Some medium-sized dogs can jump considerably higher than their size might suggest.
Climbing behaviour: Certain dogs use rails, battens or nearby objects for leverage.
Previous escape behaviour: A dog that has already learned to jump a gate may require a more substantial solution.
Nearby objects: Bins, retaining walls, garden beds or outdoor equipment can effectively reduce the gate's usable height.
Animal Welfare Victoria's Code of Practice recommends fencing of around 1.8 metres for yards or dog enclosures, while noting that shorter fencing may be suitable for small dogs or dogs unable to jump or climb. The important principle is that the barrier must be high enough to contain the particular dog.
For a small dog that has never shown an interest in jumping, a lower pedestrian gate may sometimes be adequate. However, choosing a gate simply because it is several times taller than the dog's shoulder height can be misleading.
Medium and large dogs usually benefit from greater height, particularly if they can stand against the gate with their front paws.
For athletic dogs or proven jumpers, a taller continuous barrier may be more appropriate than a standard pedestrian gate.
You should also consider the gate's effective height. A 1.8 m gate does not function like a 1.8 m barrier if a raised garden bed, air-conditioning unit, retaining wall or storage box gives the dog an elevated launching point beside it.
How Small Should the Gaps in a Dog-Safe Side Gate Be?
There is no single gap measurement that is suitable for every dog. A Chihuahua puppy, dachshund and Labrador have very different body proportions, so spacing should be assessed against the particular dog using the gate.
Look carefully at:
Spacing between vertical battens.
The opening beside the hinge post.
The opening beside the latch post.
Decorative cut-outs or screens.
Openings around rails.
The space underneath the gate.
A useful practical rule is that the opening should be too small for the dog's head, shoulders or paws to pass through or become trapped.
This matters because a dog does not necessarily need its entire body to fit through a gap initially. If it can push its head or shoulders through, it may be able to force the opening further or become caught.
The American Kennel Club similarly recommends selecting gates with openings small enough to prevent a dog's head or paws becoming trapped.
For puppies and particularly small dogs, suitable designs may include:
Closely spaced vertical aluminium battens.
Solid aluminium infill.
Timber paling gates.
Timber battens with reduced spacing.
A solid lower kick panel with more open battens above.
Special rules can apply to declared dangerous or restricted dogs. Victorian regulations covering some prescribed enclosures specify construction details including 50 mm mesh openings, but this should not be interpreted as a universal 50 mm rule for an ordinary residential pet gate.
How Much Clearance Should There Be Under a Side Gate?
The bottom of the gate is one of the most frequently overlooked escape points. Even if the vertical battens are closely spaced, a dog may be able to:
Push its nose beneath the gate.
Scratch at soil and gradually enlarge the opening.
Dig underneath the gate.
Use an opening created by uneven ground.
Exploit a larger clearance at one end of a sloping path.
Residential fencing should prevent dogs escaping underneath and notes that dogs that dig may require measures such as buried wire or concrete footings.
Good site design can therefore be just as important as the gate itself. Where practical, consider:
Keeping bottom clearance consistent throughout the gate movement.
Installing the gate over concrete or paving.
Avoiding soft, easily excavated ground directly beneath the gate.
Incorporating a suitable lower rail or solid infill.
Accounting for driveway or pathway slopes before fabrication.
Using a fixed panel where the landscape creates an unavoidable opening beside the gate.
Accurate site measurement becomes particularly important here. Rather than measuring only the distance between two posts, the installer should consider the completed ground level across the entire gate opening. A custom-manufactured gate can then be designed around an unusual side path, slope or level change.
What Type of Latch Is Best for a Side Gate Used Around Dogs?
The latch can become the weakest part of an otherwise well-designed side gate for dogs.
A suitable latch should engage positively when the gate closes, remain correctly aligned and resist being pushed or manipulated by the dog. It should also be easy enough to use that household members do not become tempted to leave the gate unlatched.
Common options include:
Standard mechanical gate latch - A straightforward option for everyday pedestrian access, provided the release mechanism is positioned where the dog cannot easily operate it with its nose or paws.
Key-lockable latch - Useful where greater security is required, especially when the side gate opens towards a street, driveway or public area.
Self-latching gate hardware - A self-latching mechanism helps reduce the possibility of someone pulling the gate closed without actually securing it.
Electric or smart access - Homes requiring greater access flexibility may use a keypad, RFID credential, intercom or smart-access system. This can be especially useful where family members, carers, gardeners or other regular visitors need controlled access.
Whitehorse City Council advises that dogs should be kept behind an escape-proof barrier and recommends a locked rear gate where appropriate.
Requirements are considerably stricter for some restricted or declared dangerous dogs. Victorian rules can require self-closing, self-latching and lockable gates in prescribed circumstances. Owners of dogs covered by these classifications should confirm their obligations with their local council rather than relying on ordinary domestic gate advice.
Should a Dog-Safe Side Gate Be Self-Closing?
Not every ordinary residential side gate needs to be self-closing, but a gate closer can provide another useful layer of protection. It may be particularly worthwhile where:
Children regularly use the gate.
Tradespeople enter the backyard.
Gardeners or cleaners visit the property.
Several household members use the side access.
The dog tends to rush towards an open gate.
Visitors may not remember to manually latch the gate.
The closer should be selected and adjusted carefully. A gate that slowly swings towards the post but stops a few millimetres before engaging the latch is not genuinely self-securing.
A practical combination can be:
Gate closer + positive self-latching mechanism + optional key lock
Which Side Gate Styles Work Best for Different Types of Dogs?
There is no single best gate material for every dog. The right design depends on size, behaviour, visibility requirements and how the gate needs to complement the home.
Some practical options include:
Solid aluminium gate - ideal where small openings and visual screening are priorities. A solid panel removes most opportunities for a dog to push its head or paws through the gate. Reduced visibility can also help where a dog becomes highly excited by passing pedestrians or other animals.
Closely spaced vertical aluminium battens - balance airflow and containment. Vertical battens create a contemporary appearance while retaining some light and ventilation. Spacing can be customised to the dog rather than relying on a standard configuration.
Timber batten gate - suited to warmer residential designs. Timber works well with many contemporary and traditional Melbourne homes. Appropriate spacing is important, as is allowing for natural timber movement over time.
Tubular steel or aluminium gate - useful where openness is preferred. This style can work well for larger dogs where visibility is not a problem. Closer spacing may be necessary if puppies or smaller pets also use the yard.
Part-solid, part-open gate - a practical compromise. A solid lower section can prevent smaller dogs placing their head or paws through the gate while open battens above maintain airflow and natural light.
Material selection should also consider scratching, chewing, jumping and weather exposure rather than dog size alone.
What Other Details Make a Side Gate More Dog-Safe?
Small construction details can create escape points even when the main gate panel appears secure. For that reason, inspect the entire opening rather than assessing only the central section of the gate. Important details include:
Check the hinge-side gap. A tightly designed latch side does little good if there is a large opening beside exposed hinges.
Avoid horizontal footholds for climbing dogs. Horizontal rails or framing can sometimes provide leverage for dogs that climb rather than simply jump.
Keep bins and outdoor furniture away from the gate. A bin, storage box or garden structure can become an unintended platform and significantly reduce effective gate height.
Check around both posts for digging. Dogs frequently investigate corners and edges where fencing meets posts rather than digging directly beneath the centre of a gate.
Consider sightlines. If your dog becomes highly reactive to pedestrians, neighbouring animals or street activity, reducing visibility at the lower part of the gate may help create a calmer boundary.
Check alignment periodically. Hinges can loosen, timber can move and posts can shift slightly over time. A secure gate should therefore be inspected periodically to make sure the latch still engages correctly.
Build the Side Gate Around How Your Household Actually Uses It
Dog containment matters, but a secure gate also needs to work conveniently every day. A gate that is too narrow for a wheelie bin, difficult to unlock or awkward to close may eventually be wedged or left open, defeating the purpose of the containment design.
LATITUDE Fencing & Gates can customise:
Aluminium side and pedestrian gates.
Timber side gates.
Closely spaced battens.
Solid or partially solid infills.
Lockable and self-latching hardware.
Gate closers.
Keypad and smart-access systems.
Intercom integration.
Matching gates and boundary fencing.
A well-designed side gate for dogs should therefore suit the animal, property and people using it rather than applying one standard configuration to every home.

FAQs
Is a 1.2 m side gate high enough for a dog?
It may be suitable for some small dogs that do not jump or climb, but there is no universal minimum that works for every household dog. Consider the dog's size, jumping ability, previous behaviour and nearby objects that could provide a launching point. Victorian animal-welfare guidance uses approximately 1.8 m as a general fencing benchmark.
What is the safest gate style for a small dog?
Solid gates or closely spaced vertical battens generally make containment easier because they minimise openings. A solid lower section with open battens above can also work where you want more airflow and light.
How do I stop my dog digging underneath a side gate?
Start by reducing unnecessary ground clearance and addressing soft soil beneath the gate. Depending on the site and the dog's behaviour, paving, concrete, buried barriers or appropriately designed lower infill may be considered.
Is a self-closing gate better for dog owners?
It can be. Self-closing hardware is particularly useful where children, visitors, tradespeople or multiple family members regularly use the gate. The closer should be adjusted so the gate reliably reaches and engages the latch.
Can LATITUDE add a keypad or smart lock to a dog-safe gate?
Yes. Depending on the gate design and access requirements, LATITUDE can integrate options such as keypads, intercoms and smart-access systems alongside suitable gate hardware. This can provide convenient controlled access without relying on household members leaving a gate unlocked.
