Is my dog in "HEAT"

[ZEROPILOT]

I have a 10 month old Chihuahua.
She was at the vet last week for some ear medication on Wednesday.
On Friday I noticed that her "Female area" is swollen looking and maybe 2 or 3 times it's original size. There is no blood, but I'm thinking maybe she is sexually mature now?
She seems to be in no distress at all about it.
The information I have is from the internet.
I was about to make an emergency vet call.
(I have very little experience with female dogs.)

Yes that sounds typical of a female in heat. They won't bleed much especially smaller breeds. The swelling is a dead giveaway.

Once all is set and done it will go down to what it was before her heat.

Agreed. My small dog bleeds very little if at all.

She's 2.8 pounds.

Oh my gosh. That is so small!

Yep , the swelling is the clue ! That's really tiny , must be what they call "tea cup" size ?
