Quick Answer: Fence first — no amount of training reliably replaces physical containment when a motivated dog wants to leave. For boundary awareness within a fenced yard, use flag markers at the perimeter and reward the dog heavily for not approaching them. Adequate enrichment is the biggest factor: a dog who has sufficient exercise, snuffle mat meals, and a frozen lick mat has dramatically less motivation to seek entertainment beyond the fence.
Physical Containment First
Electronic fences cause fear and pain and can fail. Standard fencing is the most reliable containment. For dogs who jump: height extensions, roller bars on top. For dogs who dig: L-footer extensions buried at the base.
The Enrichment Prevention
Most yard escapes are boredom-driven. A dog with a snuffle mat meal, a frozen lick mat, and daily walks rarely attempts fence escape — there's simply no motivation strong enough to compete with their established enrichment routine.
