My dog is 9months old. Recently he’s been having mucus come out his nose, throwing up yellow foam, and has really thick saliva.

It sounds as Choco is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking him to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.
