My Dog Vomits in the Mornings - What Do I do?

By Dr. Caitlin O’Donoghue

Scrubbing a rug or mopping a floor is nobody’s idea of a perfect morning. But if your dog vomits in the morning, chances are you’re not alone. Bilious vomiting, which is what this is called, is not terribly uncommon. Essentially, when stomach acid and bile build up in a dog’s stomach, they can cause the dog to vomit. This typically happens after going for several hours without food. Try these two simple things to avoid waking up to your dog’s puke.

Late Night Snack

Many dogs will stop vomiting first thing in the morning if we give them a midnight snack just before bed. This works to help prevent that stomach acid build up. Some people will also leave out puzzle boxes or kong toys with snacks in them that dogs can work on overnight. This can be especially helpful for dogs that wake their humans up for food in the middle of the night.


Other dogs may need an antacid to help treat their early morning vomiting. Famotidine and omeprazole are common over-the-counter antacids used for bilious vomiting in dogs. Frequently, they only need a dose a night to prevent the joys of early morning vomit piles. However, it is important to know that not all early morning vomiting is caused by stomach acid build-up, so please consult your vet before assuming antacids is the right approach.  If your pup has vomited more than one time in a row, is lethargic, having diarrhea, or may have gotten into something, they should be evaluated by a veterinarian to ensure that there is not something more complicated going on. There are a variety of of other issues that can cause pups to vomit, and sometimes our furry friends need more than just over-the-counter assistance. Please contact us or your veterinarian if the vomit persists for further guidance.
