Dogs in Heat

Question
First time owner of a female dog, Lhasa Apso, about 6-7 months old.  Excellent health and up to date on shots, etc.

Appears to be heat, with slightly bloody drippings from her vagina.  With slight swelling.

Messy around the house.  

How do we care for Zoey during this period?
How long does the heat period last?
How often does it occur?
Is there something to do like pads or diapers?
When to have her spayed?

Need help for beginners with a female, owned mailes for over 40 years.

Love dogs.

Roy
