Start lightly and add accordingly to when you can just start to pick it up in the back ground.
It' is probably not that subtle to canines, so it might be a good idea not to rely just on your nose when using it.
I can barely smell musk ketone, and to me, it has a weak powdery, floral smell (and I couldn't smell it at all after covid), but I can smell most other musks well. I've read that 30% of people are anosmic to musk ketone, and among the few people people whom I asked to smell it (as crystals and as 10% ethanol solution) most couldn't smell it at all, but one friend said that it had a very strong sweetish, musky smell that persisted on her skin for a couple of days where she put a tiny dab, even after showering and scrubbing.
