My puppy isn't eating, throwing up, and has crusty lips. What's wrong?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | unspayed | 3 months and 21 days old | 30 lbs

My dog Bernadette is 4 months old, maybe slightly under and is a chocolate lab. Shes typically very responsive, positive, and upbeat but a couple days ago I noticed she barely had ate out of her bowl, and thats unusual. Shes not been acting like herself and is just sitting around. The last 2 days I dont think shes pooped, or ate anything, ive tried. She has been drinking water which did slow some today. Shes throwing up yellow fluid/mucus? Also has dark goo/ crusty stuff around her lips. Help?

It sounds as Bernadettet 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 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.
