If Your Dog Loves to Swim, This Blog's for You!

 A few years ago, I had a client whose neighbor lost their dog to water toxicity.  While not super common, it does happen and just this week, I had another client reach out to tell me that her sister's dog nearly died from water toxicity following a day at the beach.  Given the unseasonably warm weather we've been having, and the number of clients headed to the beach or uncovering their swimming pools, it seemed like a good time to revisit this topic.

Acute water intoxication is somewhat rare but most commonly seen in dogs that love to play in water. It can actually occur anytime an animal ingests a large quantity of water quickly. High risk dogs are those that engage in water play, including those who like to bite at sprinklers or play with the garden hose. Dogs who love to retrieve round toys in water, or compete with other dogs to get those water toys are also at risk of ingesting large quantities of water as their mouths are open when retrieving.

So, what are the symptoms of water intoxication?  They are: loss of coordination, lethargy, bloating, vomiting, glazed eyes, excessive salivation, difficulty breathing, seizures, and coma.

Once a dog begins showing symptoms of water intoxication, it is critical to get them veterinary care immediately if they are to recover. When a dog ingests too much water, this results in a condition called "hyponatremia," which is excessively low sodium levels in the blood. Too much water causes unbalanced electrolytes and dilutes the sodium storage in the fluid around the cells. Cells fill with water which causes swelling that affects the nervous system since sodium helps maintain blood pressure and is important to nerve and muscle function. It is also the case that dogs who play in salt water for extended periods of time may ingest too much salt water leading to hypernatremia.

If you have a water-loving dog, or one who will retrieve a toy tossed in the water over and over, you need to monitor their water activity and insist on breaks.  Even if they just love playing in the sprinklers or biting a garden hose, watch them for taking on too much water. Even a dog who quickly empties a water bowl following brisk play or exercise is a risk for water intoxication.  Wait to refill that bowl until the dog has cooled down and the water they drank has been properly absorbed.

Prevention is obviously the best course of action with this issue. If your water loving dog does however, show any of the above symptoms, get them to the vet quickly. 

As always, if you have questions about your pet's behavior, you know where to find me.
