Both of our Border Collies have a level of anxiety - one is nervous of strangers and the other reacts to her nervousness and can be snappy. Wearing the yellow nervous bandana and harness means that most people don't approach the dogs without asking if it's okay first.
Great tool for allowing people to see beyond the quiet dog disposition. People see and read and ask before approaching which is exactly what my anxious dog needs to gain confidence in an action packed world!
Bought one of these excellent bandanas for our girl who is a rescue and still adjusting to people and large groups and it has worked a treat in public settings! People now read the bandana and give us some space or if they want to approach ask first before coming closer; especially kids, parents are stopping them and older kids like teenagers ask as well :) definitely recommend!
