1. Take the time
To generate reliable recall, it’s important to take the time to build a 100% positive experience with your chosen recall cue (command) with high value rewards (such as chicken or hot dog). If your dog’s recall isn’t rewarded often and well enough then your dog will be more likely to continue to do their own thing, i.e. playing with other dogs or sniffing something of great interest which is terribly reinforcing in itself, and ignore your call.
