Mimsly will recall 100% of the time within the backyard, or even out in public on her 10m long lead. Once the lead comes off, she will do recalls up to 5m… but a cm more than this and she will run off, get the zoomies for 2-3 mins and only recall to one of us after that point. Have tried all sorts of very quiet parks, and very tasty treats for encouragement.
