Why does my dog throw up bile in the morning and her dinner?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | spayed | 1 year old | 13 lbs

Since mid December my dog would randomly throw up bile in the morning (she did this roughly 5 mornings from mid December to Jan 4th). I began to think it was the food I was feeding her and the vet tech said I should try natural balance LID food instead of blue buffalo. I've been feeding her chicken & rice since 1/4/19 and slowing introducing new food. She hasn't puked since but last night she threw up all her dinner around 1am. Is it her food causing her to puke? She is otherwise acting normal.

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!

    You could try to feed her later at night and earlier in the morning as sometimes intense gastric acidity can be responsible for that. A bland diet (boiled chicken and rice )might help as well. Please do not hesitate to contact us again on the forum or by requesting a consultation (where you can post pictures ) if you have any more questions or to discuss it any further.

    Hello, I am sorry to hear about Veb. Vomiting is a nonspecific sign in dogs. It can be a sign of a problem with the GI tract or other organs, such as kidney and liver. A variety of things can cause gastritis. If you have recently made changed his diet or opened a new bag of food this could be causing some irritation. Additionally although he may not have gotten into anything in the house, if he ate leaves or something during a walk this could also lead to irritation. Because Veb is acting ok otherwise and has a good appetite I think that another abnormality (such as liver or kidney disease) is unlikely. There is a phenomenon called bilous vomiting, where the bile and acid on an empty stomach makes dogs feel nauseous overnight. In these cases feeding a small meal/snack before bed can help. If Veb continues to act ok and have a good appetite I think it is ok to continue monitoring him for improvement. If any other symptoms develop I would recommend having him evaluated by your veterinarian so that they can examine him and determine the need for other diagnostics. Hope this helps, good luck
