Guild Wars 2

I tried to complete the quest given by Kennel master Warsnout, but I was unable to “check-out” another dog after the first one. Even though I saw the first dog return to its kennel after doing its run, I got the message “I’m not giving you another one until the last one comes back”. I waited approx. 5 minutes to see if it would reset, and it did not.

Looks like this one is still bugged. I was attempting to do it today but the NPC wouldn’t let me release any of the hounds. I started looking around and I noticed one of the hounds was already missing. I never even released one. Lucky for me, a random player told me that I can do it without the hounds and proceeded to show me the way. Thank you kind stranger.

Basically there’s a cave near the bridge area south-west of the heart. Just go inside it and kill the Separatists. Hope that helps.
