Summer is here, so it's more important than ever to be conscious of your dog's and cat's water intake. But how much water, exactly, do dogs and cats need to take in every day? Dogs and cats need different amounts of water based on their body weight, activity, and daily food intake. You can follow some rough guidelines to make sure your pet gets enough fresh water every day, but it's also important to look at how your cat and dog drink water in addition to the amount.
Why is water important?
Water is important for animals for two reasons: hydration and body temperature control. If your pet dehydrates from a lack of fresh water, it can impair cell function. If your dog is playing in the hot sun, it can overheat. Lack of hydration can cause dizziness, muscle cramps, disorientation, nausea, and other health problems.

Dehydration can also dry out skin and fur, further harming your pet. Proper hydration includes serving water at the right temperature. Iced water might take longer to leave the stomach and get to the muscles, so you can consider serving your pet chilled water.
Some medical issues like kidney disease or Cushing's disease can be caused or made worse by a lack of fresh, clean water.
How much water should a dog drink?
Adult dogs should get about one ounce of clean water per day for every pound of body weight. To do the math, a 20-pound dog will need 20 ounces of fresh water, which is the equivalent of 2.5 cups. One cup of water is 8 ounces. You'll also need to take into consideration your dog's exertion levels throughout the day. For example, if your healthy dog is running and playing in the hot sun, it's going to pant and lose more water and nutrients lost in the process.
If your dog is laying around the house, sleeping, or otherwise being mostly inactive during the winter months, your dog will need less water and need to replenish fewer nutrients than if it were panting intensely. A dog drinking bowl that holds a certain amount can help you determine if your dog's water intake is sufficient.
How much water for cats?
Cats should get 3.5 to 4.5 ounces of water per day for every five pounds of body weight. As with dogs, you will need to consider a cat's activity level, how hot it is, your home's air conditioning or heating situation, and whether you serve your pet dry or wet cat food. In addition to skin and fur problems, lack of water consumption can magnify existing health problems in cats, such as diarrhea, kidney problems, diabetes, and hyperthyroidism.
What about dry or wet food?
If you're serving wet or dry pet food, that will impact how much water your cat or dog needs. A dog or cat who eats a wet cat or dog food receives some hydration benefits from that as well. Dry food has almost no water content. You can pour some fresh water or even bone broth or chicken broth over dry food. In addition to making some dry food more enticing for animals, adding water in. the form of broth will help keep your pets adequately hydrated. Don't forget that leaving food and water out all day will lead to more frequent needs to defecate and urinate.
Do bowls matter?
Serving your pet water in a plastic water bowl can lead to health problems. If the bowl becomes scratched and the outer seal is broken, bacteria can form in these areas. Some pet experts believe that plastic drinking bowls leech BPA, lead, or other harmful chemicals into the water over time. A nonporous stainless steel water bowl eliminates these problems.
You might also want to look into water bowls with fountains. Cats are feral animals and drinking water that's been standing for several hours is not as inviting as water that comes from a gently gurgling source. In addition to keeping water circulating, a fountain bowl makes a soft sound that attracts cats and can lead to their drinking more often.
Whether you buy a water or food bowl made of plastic, stainless steel, ceramic, silicone, or other material, check for any certifications or warnings on labels. Inspect bowls frequently for cracks or chips that can allow bacteria growth. Use a water bowl that keeps more water than your pet needs each day in it. This will make sure your pet has enough water if there's a spillage, and will make the water source more attractive than if the pet has to lick the surface of the bowl to get the last few drops of water it wants.
Add a humidifier
In addition to keeping your pet properly hydrated, consider adding a humidifier to your house. This will help make your pets less thirsty if you leave during the day and leave the heat on. Humidifying can also help with skin conditioning, dry eyes, and allergies.
Learn the symptoms of dehydration
A dehydrated dog will exhibit symptoms such as loss of skin elasticity, loss of appetite, vomiting with or without diarrhea, lethargy, panting, dry nose, or sticky gums. A dehydrated cat will have similar symptoms including less urination and an elevated heart rate. Cats don't usually pant, but if they are dehydrated they might.
