I cannot reproduce this issue, you can close this (but I found 1 minor issue).
.q add 9410
Go to the quest location.
Summon wolf, he does both the emotes.
He starts to run and you have to follow him.
It behaves like here: https://www.youtube.com/watch?v=4BGlnjGieUk
_Minor-issue:_ Since I am using the warmane client, and I am still a novice when it comes to extract dbc files from AC, I see that the wolf icon is not displayed correctly.
Check 3:04 of the above video on how the wolf's buff and tooltip should have been displayed.
