My 8 month old puppy has just started vomiting every night around the same time the last 4 nights. She’s acting normal but her vomit is dark brown with stringy chunks and smells like feces. what could this mean?

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