Being a young girl, who was on a team for about 3 years.. I can say that I understand completely what you mean, lol.
Have you tried any training yet with him? On air scent or cadaver? When I started on my team, they didn't ask.. so at least you have an option. They start everyone off on air scent and move on if they aren't progressing. If you haven't tried either.. just my opinion, tracking or air scent might be a starting point.. I say try out one or the other and see how he does.
There is nothing wrong with not knowing yet if you haven't been working your dog. You really don't know.. in my opinion, what your dog is good at until you try. Have you done any scent games? Have you tried any tracking games? Those might be places to start. You can always as your team lead if he can help you decide because you aren't sure. I hope you are on a team that will actually help you and not belittle or judge you.. I have been on a few of those.. hence why I am no longer there.. LOL.
Good luck!! I'm sure more experienced members will comment.
