I've had this bug happening pretty much since I started playing and bought the Husky. Whenever I feed it it gets stuck in its spot while reacting to the food, and teleports/starts moving again after that. At first I thought that's just how pets work here until I reached a point that I bought a cat on my BS and realised it doesn't do that, just keeps on moving/looting while reacting to the food. ign: Graador Short video:
This is just how the pets react upon being fed food You may try it on other pets (or ask buddies/guildmates to try it)
That's what I assumed at first too. Then I got the cat on the BS and when I'm feeding it it just keeps on following/looting without lagging in place. It does get stuck when overfed though, but usually I'm feeding the pet when its hungry. The husky does that any time it's fed, even when hungry.
