Cute wolves make a cricket-like sound when panting

I don’t know if its intended, but when dogs do their “panting”, they do this weird sound like its crickets during night. The biome name exactly is a snowy taiga, therefore they’re snowy dogs. I have no mods installed, and am playing on a vanilla server. Also i put panting in quotes, because well, i understand that the panting has this same way of going up and down in tone as crickets' cricketing, but it sounds awfully close to cricketing instead of panting.
I didn’t find any other variations of dogs in this version (ever since animal variations were being implemented), so i’m not sure if its for every type of dog or only for the snowy type.
(By the way, the sounds are played after 25 seconds into the video, it was a server so i couldn’t just pause the game to catch the sound)
