Water poisoning in dogs – when playing in water becomes dangerous

Frolicking in the water, swimming, retrieving sticks from the lake, diving enthusiastically into the waves: dogs can be real water rats. But despite all the fun, there is an underestimated danger lurking: water intoxication, technically known as “hyponatremia”. This is when the dog takes in so much water in a short space of time that the salt and mineral balance in the body is thrown out of balance.

How does water intoxication occur?

When playing fetch in water or splashing around wildly, dogs often swallow large quantities of water unnoticed. The water enters the bloodstream via the gastrointestinal tract. As a result, the ratio between water and sodium changes: The sodium concentration in the blood drops. The body cells swell – particularly dangerous in the brain.

First warning signals

The symptoms can appear shortly after playing in the water:

• Restlessness, listlessness or disorientation
• Vomiting
• Increased salivation
• Wobbly gait, staggering
• Convulsions or unconsciousness in an emergency
• Immediate measures

If you suspect water poisoning: stop the game immediately and get the dog out of the water. Seek veterinary advice! This is a life-threatening emergency. On the way: Keep the dog calm, do not encourage it to drink.

Prevention – how to stay safe while playing

• Limit the time spent playing fetch in the water.
• Take breaks ashore every now and then.
• Instead of small sticks, it is better to use floating toys that the dog can grab without swallowing a lot of water.
• Watch out for the first signs of tiredness and call it a day in good time.
• In hot temperatures, it is better to do several short sessions than one long one.

Conclusion

Water is fun, no question about it – for many dogs it is pure paradise. However, they can take in a dangerous amount of water unnoticed, especially when they are exuberant. If you know the signs and take preventative measures, you can ensure that bathing fun remains safe.
