You can't build a fence against your neighbor's fence if it touches or is attached to it unless you get explicit permission from your neighbor. Most municipalities recommend building a fence about two feet away from your neighbor's fence to allow access for fence repair and mowing.

Vinyl or PVC fences offer low-maintenance features, weather resistance, and diverse style options, ideal for security and privacy without extensive upkeep.

Check for gaps or weak spots where your dog could escape and seal them. Remove toxic plants, chemicals, and potentially hazardous items. The list includes cocoa bean mulch, which is harmful to pups if ingested.

It's also essential to provide shade and fresh water. You may want to consider installing a dog-friendly surface on concrete areas like artificial turf. Additionally, regularly inspect for potential hazards, such as sharp objects or broken glass. Most importantly, supervise your dog during outdoor time to ensure their safety.

You can use soil and gravel instead of concrete when setting fence posts. However, concrete is more durable and longer lasting, so it's worth considering if you want your fence to withstand the test of time. You should especially consider concrete if you live in a region that experiences severe weather, which can damage your fence.
