This is a weird one and I don't know what to make of it. Here is a video from a month ago. These videos are on facebook so hopefully you guys can see them.

And here is a video I took today. I've noticed she seemed a little warble-y with some mild voice changes over the last few days but then today BOOM. Much deeper.

Even her chatter, chortles, and squeals are different. Much deeper. Sadie's voice has always been very feminine and rather shrill. My ear drums are kinda thankful but really, this is just so sudden. Is it weird that my dog went into puberty and got a deeper voice so suddenly at 3 1/2 yrs of age? Is this something that needs to be looked at?

and went and hid in her crate for a few mins. Then the day after that I noticed deeper screams and whines.
