I should add that I know Lola tends to be a bit of a “free spirit” during her searches. I tried to keep the scent area pretty small but she still was all over the yard.
I haven’t used her leash (6ft) as I think it would cramp her ‘style’ so I’ve ordered a 20ft long line to try with her. I think she will still have the freedom she needs and but remain in the area at hand.
