Can you have asthma without knowing?

Thank you for your video, it was very informative. I've been trying to see if there are any other situations like me. Yesterday I took a lung test because I had my first ever asthma attack a month ago, which was caused by being in an enclosed basement with my friend's big dogs. I've never had Asthma before, so I didn't even know I was having an Asthma attack before it got worse and by the end of the day I was hyperventilating. Not a good experience. I went to see a doctor and they recommended me taking this test. My breathing came out normal, but it wasnt until they checked my asthma levels by having me inhale something that might trigger my lungs to contract? Anyway, I barely made it through level one then after level two the doctor said we would stop there. So I'm like yup, I have Asthma now. It's very strange becuase it doesn't effect me daily, it seems the only trigger I have (that I know of) is being around dogs. I knew I was allergic to dogs already, I just didn't know how allergic I was until that day. So now my next steps are finding out what else could also trigger my asthma so I can be more aware.
