First, identify the escape method
A fence that contains a beagle will not contain a husky, and a fence that stops a jumper does nothing about a digger. Before you think about material, work out what your dog actually does, because it changes the build.
Broadly there are three: the ones who go over, the ones who go under, and the ones who work the gate. A few talented dogs do all three.
For jumpers, height is the whole answer
Six feet of solid privacy fence handles the large majority of jumpers, and solid matters as much as tall: a dog that cannot see the squirrel is a dog with much less reason to launch. A four-foot ornamental fence that a dog can see straight through is an invitation for a motivated animal.
Just as important is what sits next to the fence on the inside. A woodpile, a raised bed, an air conditioning unit, or a garden bench is a launch platform, and dogs find them immediately. Keep a clear zone along the inside of the run.
For diggers, everything happens at ground level
Height is irrelevant here. What matters is the gap between the bottom of the fence and the dirt, which is exactly where standard installs leave a couple of inches for drainage and clearance.
The fixes are straightforward: run the pickets closer to grade, add a treated kickboard along the base, or bury an L-shaped dig guard that turns outward under the soil so digging leads into wire rather than open ground. Say the word digger when you get your estimate and any decent contractor will build for it.
For a big yard on a real budget, chain link still wins
Chain link has an image problem and it remains the most secure containment per dollar available. Black vinyl-coated mesh visually recedes into a treeline far more than people expect, and a properly built chain link fence with tension wire and a top rail stays tight for decades.
If the goal is a safe dog on a large lot rather than privacy from the neighbors, this is frequently the honest recommendation.
Do not neglect the gate
The gate is where most escapes actually happen, usually because it was left ajar or the latch did not seat. Self-closing hinges and a latch a dog cannot nose open are cheap at installation and impossible to retrofit elegantly.
