How much water your dog needs each day depends on several factors, including her size, diet, age, activity level, and the time of year. As a general rule, healthy dogs need from ½ to 1 ounce of water per pound of body weight each day.
To determine if your dog may be dehydrated or needs more water, lift some skin at the back of his neck and release it. If your dog is well hydrated, the skin will snap right back into place. Another test is to check your dog’s gums. Moist, slick gums indicate a good level of hydration; dry or sticky gums mean your pet’s body needs more water.
If your dog isn’t getting enough water each day, there are ways to encourage him to drink more, and most importantly, his diet needs to be high in moisture content.
If your dog tends to over-drink, which is a much less common problem, it’s important to supervise all her activities around water to insure she doesn’t develop water intoxication.
