Why is my dog suddenly throwing up yellow foamy bile late at night?

That could be caused by excessive acidity in the gastric environment, building up during the night. You could try to feed her later in the evenings (and eventually earlier in the am) and see if that helps. Should the signs persist despite this remedy, a check up at your local veterinarian would be needed to make sure she is all right otherwise.

If it seems to happen in the early morning when he hasn’t eaten in a while then it could be bilious vomiting syndrome. Feeding a late night snack could be beneficial. If this happens other times then I would consider discussing a broad spectrum dewormer with your veterinarian. If it continues then an abdominal x-ray may be an appropriate next step. Best of luck and I hope he improves soon. Thank you for using Pet Coach.

My best guess is that Ares has bilious vomiting syndrome. Bilious vomiting syndrome occurs when bile abnormally enters the stomach from the intestine, causing irritation and vomiting. The presence of bile is indicated by a watery, yellow-green substance in the vomit contents. If vomiting does not occur and the bile remains in the stomach, the irritation to the stomach can lead to gastric reflux. Vomiting is usually seen in the morning or late night, especially in dogs that are fed once daily. This might be due to prolonged periods between meals, or to related stomach inactivity, which aggravates the bile reflux. I would recommend two things: 1. Feed him a small amount of food just before food so his stomach doesn't stay empty for so many hours. Also, feeding multiple small meals throughout the day works better than feeding just once or twice a day. 2. Give him some Pepicd once a day for the next two weeks - 10mg (so 1/2 of a 20mg tablet). You can use the generic. https://www.

Poor Sadie. I definitely agree with the recommendation of getting off of her blue buffalo. Throwing up bile in the mornings is usually due to acid reflux or too much acid build up over night. You can resolve this by feeding her last meal of the day about 30-60 minutes before you go to bed and then give her Pepcid right before bedtime. You will need to ask you vet for the proper dose that would be safe for her and her medical history. The vomiting food in the middle of the night doesn't really follow that normal acid reflux trend. You could try to Pepcid and see if anything changes. If not, I would have your vet actually do an exam on her to ensure there isn't anything else going on like a parasite or blood work abnormalities. You could also talk to your vet about putting her on a prescription GI food like science diet I/D. I hope this helps!

This could be simply acid reflux since he only eats once a day. Some dogs will vomit bile when they don't eat often enough because the acid will build up in their stomachs. I would feed 2 times per day to see if this helps. If he is still vomiting bile, I would have your vet take a look at him to ensure nothing more serious is going on. Your vet could also tell you a antacid brand and dose that would be safe for him depending on his medical history. I hope this helps!

[Vomiting](https://www.petcoach.co/dog/condition/vomiting-1/) in dogs has multiple causes and can sometimes be a symptom of a greater underlying condition. In the absence of additional symptoms (lethargy, [diarrhea](https://www.petcoach.co/dog/condition/diarrhea-1/), loss of appetite, abdominal pain), most cases of vomiting can be managed at home with a bland diet fed in small frequent amounts until symptoms resolve. Gradually transition over 5-7 days to the regular diet afterwards. If vomiting persists for 24 hours or more, or if new symptoms develop, a visit to your veterinarian is recommended. That said, what you have described may be a condition known as bilious vomiting syndrome. The exact cause is unknown and it can affect dogs of any breed or age. Too long of a time between meals is thought to contribute to the condition. [Bile](https://www.petcoach.co/article/diseases-of-the-gallbladder-bile-duct-in-dogs/), which is quite irritating, may enter the empty stomach and can cause

Dogs generally vomit bile when they have an empty stomach. I recommend feeding small meals several times daily to reduce the vomiting. Or you can give a treat or two just before bed and first thing in the morning. Generally this is nothing to be overly concerned about. If she continues to vomit, doesn't feel well or starts losing weight then please take her in for and exam and bloodwork. Then if there is a problem they can start treatment right away if they find a medical issue. Thanks for using Boop by Petco to help you care for Emma.

It is very possible she has an acid reflux problem. However, other underlying illnesses should be ruled out as well, especially early stage kidney disease. I would recommend taking her in to your vet for baseline bloodwork analysis to start. If she checks out fine, then a short trial of antacids can be started to see if this helps reduce or eliminate her vomiting episodes. Feeding her smaller, more frequent meals, can also help if she has an acid reflux problem. Best of luck with Boozo. Take care.

Poor Chloe! It's possible she could have some minor GI upset going on, as it sounds like she vomited up some bile. Picking up her food for a bit and then offering a bland meal of boiled rice and chicken can help settle minor GI upset. Sometimes, dogs may also vomit if they've gone too long between meals. Breaking meals into smaller, more frequent feedings, or feeding a small treat before bed/upon waking can sometimes help. If the vomiting continues, or Chloe shows any other signs of illness such as lethargy, refusing to eat, diarrhea, etc, then a vet checkup is best to make sure there isn't a more serious issue ongoing.

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
