A fence gate can sag for several reasons. The issue often stems from the hardware, such as damaged or bent hinges, or loose screws that can no longer support the gate's weight. The gate frame itself might also have come out of square due to failing supports. Alternatively, the problem may not be the gate but the supporting fence post, which could be leaning or out of place. In many cases, fixing a sagging gate is as simple as tightening the hinge screws or upgrading to more robust hinges.

A split rail fence is not typically considered among types of dog fencing. Many dogs are small enough to slip out between or under rails, and dangerous pests like coyotes can slip in. However, adding wire mesh to a split rail fence can add the security needed for dog safety without compromising the timeless look that makes the split rail style appealing.

A horizontal fence is typically more expensive to build than a vertical fence, often costing between 10% and 20% more. The higher cost is due to the need for a higher grade of lumber and more posts to prevent the boards from sagging, which increases both material and labor expenses. Despite the higher price, horizontal fences tend to be more durable and offer a more distinct, modern look compared to the more common vertical picket style. However, they may not be the best option for privacy, as there can be slight gaps between the horizontal rails.

In addition to the fence itself, several factors can impact the overall price of putting a fence in. Consider these add-ons and necessary expenses when building your project budget. For example, additional cost factors may include:

• Removing your existing fence

• Land leveling and other site work

• Tree and stump removal

• New landscaping

• Working around underground utilities

• Painting and staining
