How to Install a Dog Fence for Large Dogs | Secure Your Yard

Large and athletic breeds test fences differently than small dogs. They jump, push, and dig, so the installation has to account for their strength. Whether you choose a visible barrier or an invisible wire, the setup follows a logical sequence: plan the boundary, set the posts or lay the loop, then verify everything works before letting your dog loose.

This guide covers both approaches, with exact measurements and the steps that matter most for big breeds.

Physical Fence: Height and Post Installation

A physical fence is the most straightforward option for large dogs, but height is the deciding factor. For most large breeds, 5 feet is the minimum; for XL or athletic dogs like Great Danes or German Shepherds, plan on 6 feet or more with an anti-climb design.

Installation starts with marking the fence line and keeping the posts aligned in a straight line. Measure post spacing before digging, using the panels or your planned wire route as the guide.

Check height and plumb as you go with a string line, tape measure, and spirit level. For extra stability, set the posts in concrete; . Attach the mesh to the end posts with cable ties, then continue along all the remaining posts.

If your dog is a digger, add underground mesh or a buried lip. One guide recommends a trench with the bottom of the mesh folded outward into a 15 cm lip, secured every 60 cm, which blocks tunneling attempts.

In-Ground Electronic Fence: Laying the Continuous Loop

An in-ground containment system works by running a single continuous loop of wire that returns to a mains-powered transmitter. The boundary must never be broken; a cut anywhere in the loop is a fault that disables the whole system.

The wire can be buried 2–3 inches below ground, laid on the surface, attached to an existing fence, or threaded through bushes and hedges. It can also run under driveways or grass-cutting areas, which keeps the boundary flexible for odd-shaped yards.

When laying the wire, keep the loop intact and return both ends to the transmitter unit. Mark the route before digging so you don’t accidentally sever the wire later during yard work. After burying, test the loop at the transmitter before pairing the collar.

Collar and Harness Fit for Large Dogs

A containment system only works if the receiver fits your dog properly. Never assume a collar fits a large breed; match neck size, weight range, and receiver type to your dog’s actual measurements.

That covers most large breeds, but not giants over 110 lbs. The brand also offers a GPS Collar Dog Fence for Medium/Large Dogs that fits neck sizes 15″–28″, which gives more flexibility for deep-chested breeds.

, and their European packaging lists models for both large and giant dogs, though that retailer information isn’t official manufacturer documentation.

Both methods are sold for large or very large dogs, but the fit always comes down to collar size and receiver weight limits rather than the system’s marketing. Measure your dog’s neck and weigh them before buying any receiver.
