The other day while playing on a primalist, my summoned wolf was named “Spot” when mousing over her. The next day while playing, she no longer had a name, and just had the generic wolf tag. I upgraded to a bear companion, and she was labelled as a generic bear tag. I thought, “No big deal, maybe I imagined Spot.”
Today, my bear is named “Splippery Ears.” Yes, spelled that way (did you mean “slippery?”).
Anyway, the report is to let you know that the naming for the summoned companions does not seem to be consistent.
