Water intoxication (Hyponatraemia)

This can happen when your dog is playing in the sea/ lake, a pool or simply drinking from a hose
It is important to remember that dogs can’t always determine when they need to stop drinking.

It’s on us owners to keep an eye on our dogs if they love playing in the water.
Some dogs love to throw themselves into waves and completely dive under water, which puts them at more risk of taking in too much water.

The condition is brought on by excessive fluid intake, which causes the body to lose sodium.
As a result, the body’s cells begin to fill with water and swell.
If the cells in the brain swell, it can affect the central nervous system, which can be fatal.

If you suspect your dog is suffering from water intoxication, you contact a vet immediately.

The first signs of water intoxication can be weakness, dizziness, loss of appetite or nausea and vomiting.
Symptoms of water intoxication can include:

  • Tiredness
  • Confusion
  • Excessive licking
  • Loss of appetite
  • Vomiting
  • Bloated stomach
  • Widened pupils and a glazed look
  • In severe cases, difficulty breathing, cramps and loss of consciousness

Smaller / high energy dogs that love to play in the water are at higher risk, because they can absorb a lot of fluid in relation to their body size.
