Breathing hard and sighing noises

[Zoodos]

Hello fellow lab lovers,

I have a question and am curious to know if you've had the same experience. As I posted in another thread, my best friend Cleo departed some time ago and there was something that intrigued me about her that I never understood. When she licked me for a while she would always start breathing heavy through her nose kind of like she was sighing. I know ive heard some people say it was because she was excited but she was really calm and usually just laying there quietly. Has anyone else witnessed this with their labbies?

Like occasional deep sighs? Or labored breathing?

Occasional deep sighs

One of my Chocolate Labs and now Sunnie made/make weird noises when they thought/think they've done something wrong or when otherwise anxious. Not something I've ever thought of as a sigh, it's a bit more strangled sounding.
