Both our vertical dog arms as well as our curved dog arms will work in most situations for containment. The straight arms are geared more for jumping only situations while the curved over "Houdini-Proof" arms are for climbers. We offer the straight arms as a secondary option for those who might prefer the aesthetic of those more or for people who may have trees or shrubs against the fence, which could get in the way of using the curved arms. The other use of the straight "Standard" arms is that they can raise your fence a foot higher than our "Houdini-Proof" for a total fence height increase of 3' which is good if your fence is very low.
Our systems designed for digging and for blocking gaps in fencing are uniquely used for the application. If you have gaps in between your pickets that your dog is slipping through then our Wide Gap System is a great choice. If you have a dog digging hold under your fence or gaps along the bottom then our Dig Proofer System is the best solution.
