OK, Perse, you forced my hand to write a longer reply.
No, loving dogs is more IEI. I do think dog owners lean more toward LSE than SLE, but my real reasons for calling LSE were from the statement "She is very factual, not expressive, quite authoritative. Really into dogs. Gets to the point quickly, is adventurous."
Being assertively "Factual" is LSE. Being literally sensing is SLE. Te vs. Se.
"Not expressive" seems more LSE. I have seen SLE's be very expressive, in both good and bad ways. Fi vs. Fe.
"quite authoritative" could go either way, but an LSE will try to convince you to do something, while an SLE will try to move you to do something.
"Really into dogs". I assume LSE on this because LSE like to order other people around, and dogs respond well to that. But this is admittedly a fine line.
"Gets to the point quickly" is more LSE, because they have thought about the best way to do something and want to implement it right away, while SLE are more about trying anything that works, and so are more open to suggestions.
"Is adventurous" is more SLE than LSE, for reasons stated in the last statement above, but the overall trend seems to be toward LSE. So, I guessed LSE.
In any case, if @
bolong is IEI, then he/she should be able to discern if the person would rather be loved or respected. Even I can tell that, after speaking to someone for a few minutes.
Try saying something like "I really respect your opinion on this" and if they nod and preen, then LSE. If they ignore the statement (because they don't trust you), then SLE.
Try saying something like "You're a great guy" and see how they react. If they do a double-take and look at you in disbelief, then SLE. If they smile and agree, then LSE.
