Why is my King Charles throwing up yellow bile? Should I worry?

If your pet has vomited this much in the past 45 minutes I would be very suspicious of a foreign body or a very intense dietary indiscretion (eating something he shouldn't have). I would recommend you start supportive care (like Famotiidne 05-1.0mg/kg every 12 hrs and a bland diet like Purina EN Gastrointestinal canned food OR boiled plain chicken and rice or cottage cheese. However there is a big possibility that this could have been a toxicity and if any more symptoms start to arise (such as ataxia (staggering) or shaking, crying out) then I highly recommend you seek a personal veterinarian for a physical examination and further diagnostics. - Dr. H

Poor Gulliver! He could have an upset stomach from too many treats. If he is otherwise acting fine, you could withhold food for the day and then try a bland diet of boiled chicken and white rice and see how he does with that. If the vomiting continues or he becomes lethargic then he needs to be seen by your vet for treatment. Hope he feels better soon!

He might have eaten something spoiled that is causing this. withhold food for 12 hours then offer Toby boiled boneless chicken and rice every 6 hours in small portions. if he is eating and not vomiting, continue with this diet for 2 days. After 2 days, you can put him back gradually on his normal food. If he continues vomiting or is not eating, take him to the vet to get treatment.

Poor Milo! If he is otherwise acting normal then you could withhold food for the day and see if the vomiting resolves. If so, then you could try a small amount of a bland diet, boiled chicken and white rice, this afternoon. Continue feeding the bland diet for a few days and the gradually transition back to his regular food. If the vomiting continues and/or he becomes lethargic then he needs to be examined by a vet for treatment. Your vet can take an x-ray, if needed, and then prescribe medications to help control the vomiting and make him feel better.

It could be due to the new food. I can give you a home remedy for Chance to se if that helps. Withhold food tonight, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the vomiting continues in the absence of food, he refuses to eat the bland diet, he vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away.

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. I would definitively recommend a veterinary check up if the signs persist or you notice diarrhea, more vomiting, lethargy or inappetence.

It could be the Tablet (is it Bravecto by any chance?) i have seen it happening before. withhold food for 12 hours then offer him boiled boneless chicken and rice every 6 hours in small portions. if he is eating and not vomiting, continue with this diet for 2 days. After 2 days, you can put him back gradually on his normal food. If he continues vomiting or is not eating, take him to the vet to get treatment.
