This might be one of the best pets ZOS has released recently, IMO. It's not constantly digging like the Bear-Dog, its cute little barks aren't loud or frequent, and it even lays down!
Many other pets are not like this...The Kindlespit Dragon Frog's fire spit is nearly ear-shattering compared to other sound effects and way too frequent. The Bear-Dog digs almost the whole time (loudly). The Dwarven Sphere I don't use on any alts because it never stops doing its loud mechanical noises. The Alliance War Dog's growl is also a bit loud and frequent for my tastes.
I don't have the lynx or the badger, so they may be good about these things too, but I just had to comment on the Wolf Pups hoping that future pets are like it.
(P.S. ZOS, please give us a pet volume slider!)
