So from the looks of it, it's 1/2in hardware cloth, and the covered roof is PVC. If your neighbor's dog (or your dog? the pic is covering up the post on my PC for some reason) is an issue, you'll certainly need to install a dig-barrier/skirt in addition to the pen. There will likely be recommendations from others on here about adding 2x2 or 4x4 welded wire to the frame as hwc *can* be not-too-difficult for large or determined predators to just rip through or off a frame.
Pre-fab stuff isn't very popular on here, but it does have its place for those who do not have the time or knowlege to build their own structures. There are usually complaints about the wood being poor quality, so if it were me, I would at least add pressure treated 2x4s or cedar all around the bottom where it would sit on the ground so it didn't rot out in a year.
