Toy Poodle adoption

I am (hopefully) about to adopt a 2-3 year old toy poodle from a rescue who was on a dog hoarding situation. She is 4.5 pounds and recovering from getting spayed. She has just had a dental cleaning and her teeth and gums are in good condition except that she has 5 missing teeth despite no gum disease or bad teeth.

The smallest dog I have ever owned is my rescue Bichon Frise. Beside special care to her teeth, what other things should I know since I have never owned a toy breed?
