How long can your dog survive without drinking water? It’s crucial that they have access to fresh water at all times. Our Cincinnati vets clarify.

Why is Water Important For Dogs?

One of the most neglected nutrients for dogs is water. Water, in contrast to meal ingredients that provide energy, vitamins, and other chemicals to help your dog’s health, is sometimes disregarded since its nutrition is more supportive than functional. This implies that while water does not provide nutrients, it is essential to how nutrients are digested, absorbed, transported, and eliminated in your dog’s body. Here are a few bodily systems in your dog that require water to function effectively:

  • Digestion: Water is present at all stages of digestion. Water in your dog’s body aids in the production of saliva, stomach acids, and bile, as well as playing a part in all stages of digestion.  
  • Cell Health: Water is one of the most important components of a cell. Without enough water in your dog’s body, the cell cycle, particularly cell development and division, will be hampered.  
  • Detoxifying: Water in your dog’s system aids in the elimination of toxins from the circulation and during digestion. The water in your dog’s body filters out harmful pollutants and excess water-soluble nutrients, which are eliminated in urine.
  • Temperature: Dogs typically don’t mind warm weather, but summer’s extreme heat and humidity can lead to a dog quickly overheating. Proper hydration is vital to your dog’s natural ability to regulate their body temperature.

How much water does a dog need?

The amount of water a dog needs can vary depending on several factors, such as its size, age, activity level, and environmental conditions. As a general guideline, dogs should have access to fresh, clean water at all times.

  • Dogs need about 1 ounce of water per pound of body weight every day.
  • A 25-pound dog needs about 25 ounces of water (3 cups) per day.
  • A 75-pound dog needs about 1.75 liters of water per day.
  • Puppies that are being weaned need to drink around half a cup of water every other hour or so.
  • Once puppies are weaned, they will start to need more water, ultimately requiring as much as a fully grown dog.

Here are some factors that can affect how much water a dog needs:

  • Activity level: Active dogs need more water than sedentary dogs.
  • Environment: Dogs that live in hot climates need more water than dogs that live in cold climates.
  • Health: Dogs with certain health conditions, such as kidney disease or diabetes, may need more or less water than other dogs.

It is important to make sure that your dog has access to fresh, clean water at all times. If you are concerned that your dog is not drinking enough water, talk to your veterinarian.

  • Weather: If you live in a temperate area, your dog will be alright without water for longer than if you live in a hot, dry, or humid region. Additional heat causes panting, which causes additional water loss.
  • Breed: Breeds with thicker coats, more active breeds, and breeds that drool often may require greater daily water intake to compensate for regular water loss. The more water your dog loses as a result of everyday activities and habits, the more water he will need to refill.
  • Lifestyle: If your dog is a lazy house puppy, they may be able to endure a longer period without water than a more active dog would. Generally speaking, the more active your dog is, the more frequently they will need water.
