Strange/Concerning Behavior in 2yo Dog

I don’t have anything useful to add, but if you are in WI the University of Wisconsin Vet School in Madison is a teaching hospital and will have specialists.

Just wanted to add another cause of teeth chattering, it is part of the canine Flehman response, to increase scent delivery to the vomeralnasal organ, very common response of males to the odor of bitches in heat (dog version of that lip curling behavior in horses). But bitches do it too, and you sometimes see it in other contexts.

This. My “pup” does the teeth chattering thing after smelling/licking one of my cat’s butts. :eek:

Has anyone thought to check for a wasp or rodent nest in the ceiling? Dogs hear things much better than we can.
