Is it a bit distressing to have a "professional" tell you that something is true when it's not?

We have wood laminate flooring in our living room. It’s really slick, and whenever our shepherd, Dakota, tries to peel out after an imaginary what-ever (squirid or cat or whatever) she wipes out and lands hard on her hip (not good, especially for a German Shepherd.) Well, I asked a long time acquaintance who has been in flooring for as long as I’ve known him (since the mid 90’s) if they made a rougher laminate floor, more like real wood.
He said “No They should, but they don’t.”
Not two weeks later, at Lowe’s, I found some. It’s ridged, more like real wood. It just kind of left me speechless…he’s a PRO! How could he not know?
