Need help with Hunter Pet

LF help with a shadowlands quest to get a hunter pet.

Taken from the wowhead comment section
this is the only tameable version of this hound’s colors. There is a dark black color and a mild greenish-grey color, both easily and readily available, but this is the only one with such a bright skin. It’s available as soon as you get the quest “A cooling Trail”, which is shortly after returning to Oribos during the Maldraxxus story campaign while leveling. A single Mawsworn Seeker will spawn in front of the cave at 38,49 with an accompanying Mawsworn Sentry, and seemingly has a lengthy respawn timer of maybe 3-4~ minutes.

If you want the only pale-skinned shadehound for your hunter, this is currently the only source. You can party sync with someone who is on this quest to get pulled into their phase.

Let me know if anyone can help with this please.
Thanks,
