I'm, guessing that since he shares some traits with humans having been a human before, like intelligence and the ability to speak, he also retained the ability to sweat. Or the author just didn't bother to find out if it would be factually correct. Not that it matters either way, it is a fantasy, and there are cute half wolf girls walking around. Sweating bears shouldn't seem so out of place. lol.
The triplets are so adorable chasing rabbits. Glad they caught one. Poor Alutina getting hit by poop afterwards. It was a happy chapter overall though.
