I'm in the midst of introducing my 2 6 month olds to the outside world. Finding it mega stressful whenever they disappear from the garden. So i've just got them some reflective quick release collars with my contact details on as i'm currently paranoid about them getting lost, Not that they've shown any sign of that yet, they're also micro chipped. Currently they're not best impressed with the collars but wondering if I should persevere with them. Thoughts?
