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.

 

What to do

What you should do if your dog keeps being sick

If your dog has been sick but is happy and bright:

• Do not feed them for a period of 6-12h after vomiting
• Allow access to water, little and often
• Feed small amounts of a bland diet, such as plain boiled chicken and rice, white fish, or scrambled eggs

If your dog can’t keep food or water down, please contact your vet.

 

Causes

Why your dog is being sick

Most common causes of vomiting in dogs

• Diet: eating something they shouldn’t, eating too much too quickly, a sudden change in food, or having an empty stomach for too long
• Food allergies or intolerances: reacting to an ingredient in food can cause vomiting, diarrhoea, skin rashes, and itchiness
• Foreign bodies: swallowing toys, sticks, clothing, or other indigestible objects may cause blockages that lead to vomiting
• Infections: viral, bacterial, or parasites (worms or protozoa) – “sickness bugs” are common and can be seasonal
• Toxins and reactions to medication: such as chocolate, grapes or raisins, and certain painkillers or wormers
• Illnesses in other organs (liver, kidneys, pancreas)

Home treatment

How to treat a vomiting dog at home

Home remedies for dogs being sick

A vomiting dog that is otherwise bright and well in themselves can be cared for at home. If your dog has mild vomiting, we recommend:

• Not feeding for 6-12h.
• Oral hydration products for dogs. This helps to avoid salt imbalances and encourages drinking. They can be given during the fasting period along with fresh water.
• Feed bland food such as plain boiled chicken, white fish with rice, sweet potato or scrambled eggs. Give this in small amounts every 2-3 hours if no more vomiting occurs.
• Prescription commercial dog food for gastrointestinal problems, such as Hill’s Prescription Diet i/d: highly digestible foods that provide all they need in the right amounts and speed recovery.
• Doing a slow transition from bland or prescription food to normal food over at least 4-5 days, once you are sure the vomiting and diarrhoea have stopped.

 

Vet treatment

Vet treatments for vomiting in dogs

If your dog is not improving at home, or things seem to be more serious, your dog should be taken to a physical vet practice. Your vet will ask you lots of questions and examine your dog to find out the cause of vomiting. They may also ask to run blood and urine tests, take x-rays or carry out an ultrasound scan on their tummy.

Treatments can include:

• Anti-sickness medication
• Stomach protectants
• Anti-acid medication
• Fluids on a drip if they are really poorly and dehydrated
• Surgery: to find out what the problem is, fix their stomach or remove any foreign objects that may be stuck.

 

Risk

Are some dogs more at risk of vomiting than others?

• Any dog of any age can develop vomiting.
• Dogs that eat things when they are out on walks, human food scraps, or have sudden changes in diet are at a higher risk.
• Certain breeds like French Bulldogs, Labradoodles, and Cockapoos are more prone to food intolerances.
• Puppies and young dogs are more likely to eat foreign bodies.
• Older dogs are at a higher risk of developing general illnesses related to the liver, kidneys, or pancreas, or have tumours.
• Scavengers are more likely to eat something toxic.
• Dogs of large breeds or with a deep chest are more prone to develop twisted stomachs.
• Dogs on long-term medication may be more likely to have ulcers or suffer from kidney or liver toxicity.

 

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
  • Kidneys: chronic kidney disease, kidney infection, kidney failure, tumours, kidney stones
  • Pancreas: pancreatitis (inflammation of the pancreas)
  • Uterus: pyometra (infection inside the uterus)
  • Prostate: abscess
  • Peritonitis: infection inside their tummy
• Severe infections in other parts of the body – Sepsis
• Ulcers in the stomach
• Tumours
• Metabolic diseases:
  • Ketoacidotic diabetes mellitus
  • Hypoadrenocorticism or Addison’s disease
• Bacterial infections in their stomach or gut:
  • Campylobacter
  • Salmonella
  • Leptospirosis
• Viral infections:
  • Rotavirus
  • Parvovirus
  • Distemper
  • Coronavirus
• Severe intestinal parasitic infestations:
