Big dogs mean significant responsibilities—especially when it comes to keeping them safe at home. In Austin, where active breeds like German Shepherds, Labradors, and Huskies are common, many homeowners face the challenge of reinforcing older fences to prevent escapes.
This guide explores practical ways to strengthen aging fences so they can withstand the strength, energy, and determination of larger dogs.
TL;DR: Reinforcing Old Fences for Big Dogs
- Inspect and repair weak posts, boards, or panels.
- Add height with extensions to prevent jumping.
- Install dig guards or buried mesh to block escape routes.
- Reinforce gates with stronger hinges and latches.
- Consider upgrades or replacement for long-term durability.

Why Bigger Dogs Challenge Old Fences
Large breeds have the strength to push against weak boards, the height to jump standard fences, and the determination to dig under barriers. Older fences—especially those with loose posts, rotting boards, or rusty joints—are particularly susceptible to damage.
Without reinforcement, these fences can quickly fail, creating serious safety risks for pets and liability issues for owners.
Step 1: Inspect and Repair Structural Weakness
Start by walking the fence line:
- Replace missing or loose boards.
- Check for rust on chain link or iron fences.
- Identify posts leaning from Austin’s clay soil shifts.

Step 2: Reinforce Fence Posts and Supports
Posts provide structural stability. If they’re weak, the whole fence is at risk.
- Add concrete footers to leaning posts.
- Brace posts with metal anchors.
- Replace severely rotted or rusted posts entirely.
Step 3: Increase Fence Height Safely
Many big dogs can clear 4–5-foot fences. Increase height to 6–8 feet with:
- Lattice or vertical extensions on wood fences.
- PVC or metal toppers for chain link.
- Angled panels that lean inward.
Always check Austin fence permit requirements before making height changes.
Step 4: Stop Digging with Ground Reinforcements
Big dogs often dig under fences. Reinforce the base with:
- Buried chicken wire or hardware cloth.
- Concrete or gravel along the fence line.
- Landscaping barriers, such as raised beds or stone edging.
Step 5: Strengthen Gates and Latches
Gates are the weakest point in most fences.
- Upgrade to heavy-duty hinges and pet-safe latches.
- Add self-closing or double-gate systems.
- Reinforce sagging gates with metal frames.

Step 6: Material-Specific Reinforcements
Wood Fences
- Replace rotting boards.
- Re-stain every 2–3 years to resist weather damage.
- Use thicker boards or add cross beams for strength.
Chain Link Fences
- Add privacy slats or welded mesh to reduce the risk of climbing.
- Install tension wires along the bottom.
- Upgrade to taller chain link panels for jumpers.
Ornamental Iron Fences
- Add mesh or panels to prevent slipping between gaps.
- Apply rust-resistant coatings for longevity.
- Weld reinforcements to weak joints.
When Reinforcement Isn’t Enough: Replacement Options
Sometimes, reinforcing isn’t cost-effective. If more than 30–40% of the fence is compromised, replacement may be the smarter investment.
Options include:
- Composite fences for durability.
- Vinyl fences for low maintenance.
- Ornamental iron fences for strength and security.
