The best under-gate dog barrier is one that extends to the ground. This effectively keeps dogs in and won't give them room to squeeze through. However, dogs that dig can still get under the barrier. Deter digging by paving the ground beneath the gate or filling it in with rocks or gravel. Be careful using wire to extend dog gates, as the sharp ends may cut or hurt your dog's paws.

Galvanized metal, vinyl, and composite fences are known to be the longest-lasting options, often surviving for over 30 years with proper care. Metal fences, including galvanized chain link and aluminum, can look great for decades because the galvanization process adds a protective coating that resists weather and pests. Similarly, vinyl and composite materials are resistant to pests and can withstand harsh weather for many years. In comparison, a typical wood fence lasts about 15 years, and a standard vinyl fence has a lifespan of 20 to 30 years.

Regular maintenance for wire fencing includes annual inspections for rust or damage, tension adjustments every two to three years, and immediate repair of any breaks or loose sections. You should also regularly check the fence posts for stability, particularly after severe weather, and make sure to remove any vegetation growing along the fence line.

Maintain your wattle fence by inspecting it at least twice per year for loose weaving and degrading branches. Replace any seriously degraded sections, ensure water drains properly around the posts, and trim any sprouting branches if you used green wood. If you notice the weave loosening, you can often tighten it by gently pushing down on the top branches. You can also apply a natural wood preservative every two to three years to extend the fence's lifespan.
