My husband is very active in SAR. He has both a live scent dog and a human remains dog and is a member of the FEMA Task Force Team, Texas Task Force 1 and the local fire department’s team.
What area are you guys in and I’ll try to locate a good training team for you to consult.
What you do is go meet with a team and learn a bit more about it by helping them out playing victim and other things. Then, if you think your dog might have what it takes, you arrange an evaluation of the dog. If he passes the evaluation, you will likely be invited to begin training with the team and working towards you testings.
There are certifications that YOU must pass and that your dog must pass in order to be on a real SAR team.
It is a lot of fun, but does require a very heavy time commitment. You will likely be training at least 3 days a week. It consumes your life, but is very rewarding.
My husband is called out by fire departments and police agencies regularly with his human remains dog and, of course, they were deployed during the hurricane in our area a couple years ago and during the wild fires in Texas.
