Beware of Water Intoxication, it is dangerous

Beware of Water Intoxication!


It is important to inform about this problem with Water Intoxication(hyponatriæmi) even through it is relatively rare that it happens, it can lead to death. Dogs in worst cases dies of it.

I have read about several dogs on social media who died of Water Intoxication. And the same history repeats again and again. They have been on a trip to a lake or to the sea where the dog has loved and enjoyed playing in the water for a long period of time, where the humans have thrown sticks into the water, which the dog gladly wanted to pick up. But suddenly the dogs got very ill, and after a few minutes later they died. Without the humans to being able to do anything.

And it really breaks my heart to hear about these stories, so I thought it was a good idea to inform about this issue.

Why does it happen? 

Water Intoxication occurs when the dog drinks too much water in a short period of time. Humans and other mammals can also get water intoxication, but the difference is, that we humans know when we should stop drinking water. While dogs do not know and therefore can drink large amounts of water without stopping. Even when the dog is playing in the garden with a water sprayer, or playing in the sea or in the pool with toys or sticks we throw into the water, can be dangerous if we do not carefully watch the dog.

If the dog or any other mammal consumes too much water in a short period of time, the body will separate too much sodium and the organs will stop working normally. Then the organs begin to absorb more water and therefore begin to swell. And at last it ends with a brain injury and that the kidneys will give up.

Water intoxication is most experienced with the smaller dogs, dogs with less body fat, energetic and well-trained dogs. But it can generally happen to all dogs.


Some of the symptoms can be:

  • Weakened coordination
  • Drowsiness
  • Clear eyes
  • Excessive salivation
  • Seizure
  • Coma
  • Bloating
  • Vomiting
  • Difficulty breathing


What should you do?

You should monitor your dog if it is very active in water, and make sure it gets regular rest breaks from the water. You should also have fresh water to give the dog regularly. This reduces the risk of your dog drinking lake / sea water, etc. And in generally the dog is not allowed to play too long in the water.

If you suspect your dog is suffering from water intoxication, you should immediately bring it to the vet.
