We all know that hydration is a key to good health. The same goes for our pets.
Like humans, an adult dog's body is comprised of about 60 percent water. For cats it's about 67 percent. When a dog loses just 10 percent of its body's fluids, bodily functions shut down; a 15 percent loss can be fatal. Cats tolerate dehydration a little better than dogs, but a loss of 20 percent can be fatal.
There's no set amount of water that your pet should drink in one day. But a good rule of thumb is that animals should take in about two and a half times more water than food per day.
