It sounds as QB 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.

Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach! Vomiting can be caused by several conditions including dietary indiscretion, pancreatitis, foreign body ingestion and obstruction, inflammatory bowel disease, among many other conditions. I recommend that you have him evaluated by a veterinarian as acute severe vomiting can be concerning for serious conditions like the ones mentioned above. Have water available at all times to try to avoid dehydration. Good luck!

This could be completely incidental and self resolving.
As a first approach, I would suggest to withhold food for the next 8-12 hours and then start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days.
I would definitively recommend a veterinary check up if the signs persist or you notice diarrhoea, more vomiting, lethargy or inappetence.

My dog keeps vomiting thick, lumpy, smelly mucus. Should I worry?

These persistent signs could be compatible with an inflammation infection of the gastrointestinal system and surrounding organs (like pancreas and liver). A clinical examination at your local veterinarian is immediately essential to confirm these clinical suspicions and treat appropriately. Antibiotics and possibly further investigations (like abdominal imaging as ultrasound or radiographs) may be needed. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

My dog is gagging and throwing up clear mucus. What's wrong?

This could be a sign of an upper respiratory infection such as kennel cough or it could indeed be a gastrointestinal problem. Kennel cough often present as gagging and mucoid discharge. Kennel cough is self limiting and usually goes away by itself within a few weeks and often does not need treatment. Should your dog have a fever or the coughing/gagging get worse or should your dog get lethargic, you need to take her to your veterinarian for an exam. Should your dog indeed vomit, you can try the following: I would fast her for 24 hours and then put her on bland food for two days, such as boiled white rice and boiled white boneless chicken meat, fed in small quantities over several feeds and then transition back to regular food slowly over a few days. If this does not clear up the vomiting, or if the vomiting increases, or if your dog gets lethargic, she needs to see a veterinarian for an exam as there may be something more serious such as an infection going on.
