Vomiting or sickness is a common problem and can affect all dogs of any age. 85% of the time it will get better by itself or with simple management.

Sickness and diarrhoea can be caused by dogs eating things they shouldn’t. This is called gastroenteritis and often clears up within 24-48 hours. It’s important to keep a vomiting dog hydrated, but hold back feeding for a few hours.

Vet treatments for vomiting in dogs

Are some dogs more at risk of vomiting than others?

Other causes of vomiting in dogs

Vomiting in dogs is a very unspecific sign, and it can be a symptom of many different conditions, such as:

• Car or motion sickness: some dogs don’t cope well when in the car and may vomit. They normally recover quickly once out of the car. Speak to your vet to get preventative treatment for this if you have to take your dog on a long car journey. Speak to an animal behaviourist if you want to train your dog to not feel sick in the car.

• Morning sickness: some dogs suffer from reflux when they have long periods between meals, and may bring up bright yellow liquid, especially in the morning. Making sure that your dog doesn’t go longer than 12 hours between their meals overnight may help reduce the frequency of morning sickness.

• Twisted stomach, or GDV (Gastric Dilation Volvulus)

• Illnesses of other organs:

  • Liver: liver failure, hepatitis, gallbladder problems, tumours
