Dog Fence.
Keeps the herd in.

No-dig fences — the ones that use spike-and-base panels or driven anchors instead of concrete-set posts — work for small to medium dogs in low-pressure situations: short-runners, leash-trained dogs that just need a visual boundary, breeds under 25 kg. They fail predictably with: large dogs (anchor pulls in soft ground), diggers (the spike anchors don't extend below the dig zone), jumpers (panel heights are usually 36-40 inches max), and any dog with separation anxiety that will work the fence systematically. Real-world: a beagle will defeat a no-dig fence in under a week, a golden retriever in less than that. For dogs reliable containment we recommend chain-link or welded wire on conventional concrete-set posts with a bottom rail or a buried apron of mesh extending 12 inches outward at grade. Invisible (underground wire) fence is a separate category and works for trained dogs of any size.

Cheapest containment by ascending budget: 1) Invisible (buried wire) fence with collar receiver — $300-800 supply for a typical lot, but requires training and doesn't stop other dogs from entering. 2) Welded-wire farm fence on steel T-posts, 4-5 ft tall — $8-15 per linear foot supply, fast install, suits rural lots. 3) Galvanized chain-link, 4-5 ft, residential — $12-20 per linear foot supply, the most-used containment fence in Canada, lasts 15-25 years. 4) Wood picket or board, 4-5 ft — $20-40/ft supply, visual boundary plus mild deterrent. Add a buried apron (12-18" of mesh laid flat outward at grade, pinned with landscape staples) for diggers — adds $2-4/ft and stops 90% of dig escapes. Skip 36" mini-rolls of garden mesh for anything bigger than a small terrier; medium dogs will push through.

The best dog fence is the one matched to your dog's size, behaviour, and your yard. Defaults that work in most cases: galvanized chain-link in 5-6 ft height with a buried mesh apron — visible, durable, and inexpensive, suits 90% of dogs from beagles to great Danes. For visual breeds (huskies, German shepherds) that escalate on what they see, choose vinyl or wood board fence at 6 ft to remove the visual trigger. For diggers (terriers, dachshunds) the bottom is the critical detail — bury an apron of welded wire 12-18 inches outward at grade, or pour a concrete mow strip. For climbers and jumpers (Belgian malinois, working dogs) add a 45° inward top extension or coyote rollers. For small dogs the issue isn't strength, it's gaps — spec 2-inch picket spacing maximum. Skip electric / shock for any dog already prone to anxiety.

Cheapest DIY dog fence: welded-wire farm fence (often called "horse fence" or "utility mesh") on driven steel T-posts. Materials for 100 linear feet of 4-foot tall containment: a 330 ft roll of 4x4 welded wire ($150-250), 12-15 T-posts ($8-12 each), a T-post driver ($40-60 rental), wire ties or clip ties ($20). Total: roughly $300-500 supply for 100 ft, install in a long weekend. The cheaper-than-cheap alternative — landscape orange snow fence on tomato stakes — works for a week and fails. For a longer-lived DIY add an 8-foot tension brace at corners and a concrete-set wood corner post; the run will hold tension and last 8-12 years. Add a buried 18-inch welded-wire apron at grade if your dog digs. For containment of dogs over 35 kg upgrade to chain-link.

Invisible (buried wire) fence with a collar receiver works reliably for trained dogs of most breeds, with two caveats: 1) it requires 2-4 weeks of consistent flag-and-leash training, not just unboxing — dogs that aren't trained run through the correction once and learn the system doesn't actually stop them; 2) it contains your dog but doesn't stop other dogs or wildlife from entering the yard, so it's not a substitute for a physical fence on roads or against off-leash dog parks. It works best for: medium and large dogs with stable temperaments, properties over 0.5 acres where physical fence is cost-prohibitive, and as a layer inside a property line fence to keep dogs away from gardens or pools. It works poorly for: anxious dogs that will accept the correction to flee, dogs under 5 kg (collars are too heavy), and any property with high-distraction borders.

For German shepherds, Belgian malinois, huskies, and other large active breeds — dogs that are visual, athletic, and capable of clearing 5 feet — the right fence is 6 feet tall, solid (no see-through), and either chain-link with privacy slats, vinyl board, or wood board. Three details matter: 1) Solid sightline — these breeds escalate on what they see; remove the trigger and the jumping behaviour drops 60-80%. 2) Top configuration — a 45° inward extension or coyote rollers prevents climb-over for the determined ones. 3) Bottom detail — bury a 12-18 inch apron of welded wire or pour a concrete mow strip, because diggers will work the perimeter. Avoid: 4-foot fence (a fit shepherd clears it standing), open picket or chain-link without slats (visual triggers), and electric-only containment (won't stop a focused working dog from running through).
