The disclosed technology includes a pet collar that can be configured to determine its geolocational position and evaluate that position with respect to the geo-fence of a predetermined, geo-fenced "safe" zone. If the collar determines that its position is inside a safe zone but is near the geo-fence, the collar can be configured to provide a warning correction. If the collar determines that it is outside a predetermined safe zone, the collar can also be configured to provide a stronger correction to discourage the pet from continuing away from the safe zone. The collar can also be configured to guide the pet back to the safe zone such as by varying the strength and/or type of correction provided based at least in part on the distance of the collar from the geo-fence.
