Diet

A common cause that will make a dog drink a lot of water is diet. Dry dog food can contain just about 5-10% of water, and your dog will need to drink plenty of fluids to make up for it. Salty foods will also make your dog thirsty, which will cause them to drink more than usual. Keep in mind that high sodium foods can be toxic to dogs. You should avoid giving your dog too much salty food - it is not good for them.

What is water intoxication?

Water intoxication can be a life-threatening health condition that can appear suddenly. It is also known as hyperhydration and water poisoning. When a dog drinks too much water, the sodium levels outside their cells get depleted. This condition is called hyponatremia. The body will want to balance itself, and it will react to low sodium levels by increasing water intake in cells. Some organs, like the liver, can sustain that. Other organs, like the brain, cannot because it is surrounded by bones.

Humans have competitions in water drinking, and there was a fatal incident involving a 28-year-old mother of three. She chugged 2 gallons of water to win a Nintendo Wii. Dogs can get water poisoning from drinking a lot of water. Even things like playing with a garden hose or playing in a stream behind your home can become dangerous if the dog ingests too much water in a short period. Make sure you always keep an eye on your dog’s water intake, and if you notice anything suspicious, call your vet immediately.
