The Danger of Water Intoxication
Swimming dogs are at risk of ingesting too much water

Last week a friend’s dog had a close call with water intoxication. Her crew was playing in a local river when one of her Border Collies emerged staggering and vomiting liquid.

Symptoms quickly worsened on the way to the vet, but after a few harrowing days, the dog was fortunate to make a full recovery.

Apparently the poor pup ingested too much water while repeatedly diving into the river, mouth open, trying to catch a ball. Drinking too much causes electrolyte levels to drop, thinning blood plasma and leading to swelling of the brain and other organs.

Before I learned about water intoxication, I thought that playing in the lake was safe if your dog was a strong swimmer. But now I know to be mindful of how my guys interact with the water and to force them to take ample breaks. Dogs can even drink too much water from playing with a lawn sprinkler.

Unfortunately water intoxication progresses quickly. Now that summer is officially here, it’s important to review the signs so you can get an affected dog to the vet as soon as possible.

Symptoms include lack of coordination, lethargy, nausea, bloating, vomiting, dilated pupils, glazed eyes, light gum color, and excessive salivation. Advanced symptoms include difficulty breathing, collapsing, loss of consciousness, and seizures.

As the weather gets warmer, stay safe. Water intoxication can affect both people and our pups.
