Teaching a Recall That Works When It Matters

Recall is the one command that saves lives — near a road, near a snake, near another dog. Most recalls fail for the same three reasons, and all three are fixable.

The three reasons it fails

The word has been burnt. It has been shouted, repeated and followed by something the dog dislikes, so it now predicts the end of fun.
Coming back ends the good thing. The dog is called only when it is time to go home, so returning reliably predicts the lead and the car.
The reward is worse than the alternative. A pat and a "good boy" does not compete with a warthog, another dog, or an interesting smell.

Start over with a new word

Pick a fresh word the dog has no history with. Then poison-proof it: the word only ever means something excellent, and it is never used for anything the dog dislikes.

Building it

Indoors, no distractions. Say the word, immediately give something outstanding — roast chicken, biltong, cheese. Not kibble. Do this fifty times over a few days with no expectation of the dog moving. You are building a reflex, not obedience.
Short distances. Say it from a metre away, pay generously when they arrive. Then across the room, then from another room.
Garden, then a quiet park on a long line. A five- or ten-metre training line lets you practise safely and prevents failed recalls, which are practice at ignoring you.
Add distraction gradually. Distance, duration and distraction — increase one at a time, never all three.

The rules that keep it working

Pay every single time, for life. This is not a trick you fade the reward on.
Never call your dog to do something it dislikes — go and fetch them for baths, nail trims and leaving the park.
Call, then release them back to play at least half the time, so returning does not predict the end.
Never punish a dog that comes back late. Whatever they did before, the coming back is the bit you are reinforcing.
Say it once. Repeating teaches that the word means nothing until the fourth time.

South African realities

Practise on a long line in enclosed spaces before trusting recall near roads, livestock or game. Many parks have loose dogs and the recall you need most is the one that works while another dog is approaching — train that specifically, with a friend's dog, before you need it.
