Why is my Dog Throwing Up?

January 19, 2021

Whether you’re looking for causes your dog might be throwing up, or how to treat them, there might be an overwhelming amount of information on the internet and you might be wondering, where do I start? When it comes to your pet’s health, the sooner you get them well, the better. It is also important that you know when your pet needs to be taken to the veterinarian, and when it might be an emergency. This is why we’ve narrowed it down to the 5 most common causes and some of their treatments, so you can get them feeling better in the blink of an eye.

If your dog seems to be vomiting white foam, this may be why. It may all be caused by indigestion, meaning that it might only be that they ate their food way too quickly. This can happen to dogs once in a while, just like it can happen to humans, but don’t worry, it’s nothing that can’t be fixed. They may also be throwing up bile in this scenario, but that just means that they have an empty, and upset stomach. A spoonful of canned pumpkin might be an ideal remedy for this occasion. If it happens too often, however, take them to your vet. Chronic vomiting may be a symptom of something more serious!

Water Intoxication

Just like eating too fast may cause indigestion, drinking too fast may cause water intoxication. This usually happens when the dog is out swimming and accidentally swallows too much water, but may also happen when they are extremely thirsty, especially after exercising, and drink too much water, too fast. Always be aware of how your dog is drinking its water after exercising, and that they are not swallowing too much water when swimming to prevent this. If your dog starts throwing up right after a day out on the pool, or after exercising, it is possible they may have water intoxication and it is important that you take them to your veterinary as soon as possible!


If your dog is throwing up white foam, drooling excessively and seems unable to poop, they might have bloat. This is a serious problem that means an emergency trip to the veterinarian. Their gums tend to be pale, but even if they are not, and you suspect they might have bloat, take them to the veterinarian right away, as this is a life threatening condition. Bloat is when your pet’s stomach is filled with gas that they are unable to release, causing their stomach to twist and putting pressure on the dog’s diaphragm. This causes difficulty to breathe and limits the circulation of blood to their heart.

Kidney Failure

If your pet is throwing up water, they may be suffering from kidney failure. This is also a very serious problem that tends to cause death. Sadly, if your dog has kidney failure, it means they have been sick for some time now, but may not have shown any noticeable symptoms. There is no known cure for kidney failure and treatments may be expensive. If you believe your dog may be suffering from kidney failure, take them to your vet for more information and to know what can be done to help your pup. Some other things to look out for, apart from vomiting water, include the excessive consumption of water, difficulty urinating or excessive urination, diarrhea, the dog may seem uninterested in food, foul breath, and depression.

Heatstroke is usually caused by being in extremely high temperatures for too long, such as being inside of a hot car, or sometimes exercising in temperatures that are too hot. This causes your dog’s temperature to rise to extremely high and dangerous temperatures, which can cause organ failure, brain damage, and even death. Symptoms include heavy panting, extreme thirst, seizures, dark red gums and/or tongue, a quick heartbeat or pulse, throwing up, excessive drooling, high body temperatures, glazed eyes, diarrhea with blood, unconsciousness, lethargy, and lack of coordination.

If you believe your pet may have heatstroke, attempt to cool down their body temperature immediately, and take them to your nearest vet. Cooling down treatments include taking them to a cool area and providing them with water in small amounts or ice cubes. It is likely the veterinarian will give them fluids through IV. You can prevent heatstroke in your pet by always providing them with water and shade when exercising, carrying around water to give them when the environment is hot, and never leaving them in an enclosed, hot, space for long periods of time, or at all if possible.

Recognize dehydration

  • Pale pink, white, or dark red gums.
  • Reduced skin elasticity.
  • Dry and sticky gums.
  • Pale lower eyelid color.
  • Longer capillary refill time.
  • Increased heart rate.
  • Lethargy.
  • Sunken or small (smaller than usual) looking eyes.
  • Concentrated urine.

Prevent Dehydration

Regardless of the cause your dog is throwing up, dehydration will always make things worse, so be sure to keep your pet hydrated while they get better, or on the way to the veterinarian or hospital. This should not be done by giving them excessive amounts of water, as they will most likely only throw it back up. Instead, give them water in very small amounts, and in a regular manner. You can also give them small ice cubes that they can lick at their own pace, but just like the water, do not feed them too many. An ice cube or a spoonful of water every 15 minutes should be a great start. If your dog continues to vomit, it is time for the vet. If they have not vomited for over 2 hours, continue giving them water, and after 12-24 hours of not vomiting, begin giving them soft foods, also in small amounts. If they begin throwing up again, stop feeding them and continue with the water while you take them to your veterinarian.

Whatever the cause, always visit your veterinarian to make sure you are providing them with the correct treatment for your dog, given that, just like humans, dogs may need special treatments as well. If your dog vomits too often, take them to your vet immediately! You can find more causes and treatments on dog vomitting here. We hope your pup gets well soon!
