Canine Water Intoxication

What is Water Intoxication?

Water intoxication, also known as hyponatremia, occurs when a dog ingests an excessive amount of water in a short period. This can dilute the sodium levels in their body, disrupting normal bodily functions. While rare, it can develop quickly and be life-threatening.

Signs to Watch For:

• Loss of coordination

• Lethargy or weakness

• Pale gums

• Vomiting

• Bloating

• Glazed eyes or confusion

• Excessive drooling

• Seizures

If you notice any of these symptoms after swimming or water play, seek veterinary help immediately.

How to Reduce the Risk:

• Always supervise water play, especially with enthusiastic or high-drive dogs.

• Limit the amount of time your dog spends in the water to avoid overexertion and excessive water ingestion.

• Use flatter, less buoyant toys for retrieving—high-floating balls can encourage gulping.

• Be mindful of activities that encourage open-mouth water biting, such as playing with hose sprays or sprinklers, as these can also lead to excess water ingestion.

• Incorporate regular rest breaks and watch for signs that your dog may be tiring or overly fixated on the activity.

Swimming can be an excellent part of your dog’s summer fitness routine when done safely and in moderation. A bit of awareness goes a long way in keeping your dog healthy, happy, and safe in the water.
