Okay, so it seems basic right? Dogs stick their tongues out to regulate temperature (when, of course they aren't using it to sass you behind your back). I also know dogs with no teeth with stick their tongues out cuz there's nothing to hold it back. But I have 2 chihuahuas and have noticed, that as time goes on - they both stick their tongues out!
Sometimes it's before I put their bowls down. Okay, understandable.
Most of the time, it's when they are very tired. Okay, we've all been there.
But sometimes - they just stick 'em out. For no apparent reason to me.
I don't remember them doing it as much as they do now, either.
It doesn't concern me as a health issue - I was just curious - does anyone else's dog do this? And do you know why?
