It could also be about what is in your emails. Are you talking about what a great dog you have or that YOU want to serve the community. Most SAR teams view the dog as a tool and it is the people they are more interested in. That is because they want someone who will stay on and get another dog or find a way to support the team in other ways if the dog is not suitable.
Nope, I am just saying I am interested in getting involved actively as a SAR team with my young male.
