Why is my 9-year-old Great Dane vomiting clear mucus after eating?

Updated on September 23rd, 2025

Pet's info: Dog | Great Dane | Female | unspayed | 9 years and 11 months old | 80 lbs

Hi My Great Dane has been vomiting a clear mucous liquid after food for a while now. Sometimes there is a little food in the comit but really not a lot. Other than the vomiting she is healthy and in a good condition. She is about 9 years old.

It sounds as Thandi 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. if the vet thinks it is more serious she will need a blood test and possibly an ultrasound in order to find out what is wrong.
