Posts for a horizontal fence should be no more than 6 feet apart. Wood pickets are not as strong when mounted horizontally as when mounted vertically. As such, the fence panels on a horizontal fence can’t cover the same span between posts as a vertical fence can. If you install the posts further apart on a horizontal fence, the fence will lose stability, making the boards more likely to sag. 

The first step in choosing a reputable dog fencing company is to confirm that the professional has experience in your particular area and maintains positive reviews online. You should also check the Better Business Bureau’s (BBB) website to see if they have accrued customer complaints in the past. Additionally, you can ask the following questions to qualify the pro:

• Do you have experience installing the specific fence material I want?

• Will you pull permits for the installation?

• Will you help get a survey done to make sure I build on my property?

• Do you have a list of referrals?

The cheapest farm fences are typically wire fences, which cost less to install than traditional lumber fences. Barbed wire is one of the most inexpensive options due to its simple materials, making it a good choice for low budgets. It is suitable for confining docile animals in large spaces, as it provides a visual barrier and a mild deterrent. Other options like hog wire and woven wire fences are also cost-effective because they require less lumber than a full wooden fence. These types of wire fences are strong, long-lasting, and relatively easy to repair, though they are often considered less aesthetically pleasing than wood.

A wrought iron fence is generally considered a worthwhile investment, provided the cost fits your budget and its characteristics meet your needs. While it is an expensive material, its exceptional durability and longevity mean you can save money over time by not having to replace it.

Key benefits include:

• Durability and Security: Wrought iron is strong and provides excellent security for your home.

• Longevity: With proper maintenance, it can last a lifetime or longer.

• Aesthetics: It offers a classy, timeless, and elegant look that can boost your home's curb appeal and property value, especially when complementing brick or stone architecture.

However, it's important to note that wrought iron fencing does not offer much privacy. If professionally installed and maintained, it is a sound long-term investment.
