How Important Is Water to a Dogs Digestion?

Water is important to pretty much every living thing, and dogs are no exception. An appropriate amount of water in a dog's diet is important to prevent dehydration and keep the dog eating and living healthy. In conditions of extreme activity or heat, a dog will need more water, but a good rule of thumb for daily consumption is about an ounce per day per pound the dog weighs.

  1. The Basics

    • Water is almost as important to digestion as food itself. In a dog, as in other mammals, water is the the primary component of blood, the vehicle that carries nutrients from food throughout the body. This means metabolization will not occur properly without adequate water. A dog not getting enough water may exhibit a loss of appetite or have uncomfortable or difficult bowel movements. In addition to keeping the digestive process running smoothly, water prevents dehydration and a variety of heat-related issues that dogs can suffer.

    Dehydration

    • A dog that does not take in enough water to replace lost fluids will eventually begin suffering the effects of dehydration. Dehydration can mean reduction in the dog's appetite, dry mouth, lethargy, sunken eyes and even changes in the dog's mood. Symptoms like diarrhea and vomiting increase fluid loss, so if your dog has been ill, he may need more water than usual to make sure he is adequately replacing his lost fluids. It's important to control a dog's water intake when he is dehydrated, as he may drink too much and make himself sick.

    Diarrhea and Vomiting

    • The two most obvious signs that a dog is having digestive problems are diarrhea and vomiting. They can be caused by a change in diet, ingestion of spoiled food, certain medications, infection or disease. These can both increase a dog's fluid loss and make it more difficult for the dog to replace lost fluids. To minimize the risk of developing these symptoms, it's best to dispose of food where the dog cannot get to it and prevent the dog accessing potentially contaminated water sources. If the dog does develop these symptoms, though, it's usually best to avoid giving him food for 12 to 24 hours and provide plenty of clean water to prevent dehydration.

    Contamination

    • The toilet is a poor substitute for a good water dish.

      Some of the most common sources for bacterial infection for a dog, in the home, are the kitchen trash and the toilet. Dogs don't really know the difference between a fresh steak and a scrap of fat that has been lying in the trash for a day and a half. The best way to prevent a dog eating from the trash is to keep the trash can in a pantry or cabinet where the dog cannot access it. If this isn't possible, a can with a lid can work as a deterrent, as well. Likewise, drinking from the toilet may be convenient, but toilets can contain bacteria that will have a very negative effect on your dog's digestion. Keep the lid closed or shut the bathroom door so the dog cannot get in.
