Pet Hydration 101

Keeping pets hydrated is important all year long, but pet parents need to pay particular attention to pet hydration as temperatures start to climb. Water is essential to your pet’s overall nutritional needs, so our team at Bayside Animal Hospital has put together this primer on the importance of keeping pets hydrated.
Beyond Thirst: Why Pets Need Water
Drinking water isn’t just about quenching thirst. Our pets, just like us, need water to support vital bodily functions, including:
- Temperature regulation
- Digestion
- Organ health
- Nutrient transport
- Joint lubrication
- Cushioning for the brain and spinal cord
Looking at this list, it’s easy to understand why lack of water can lead to serious health problems, including organ failure, heatstroke, and other health conditions.
Watch for These Signs of Dehydration in Pets
When pets are dehydrated, they can display a range of symptoms depending on the severity of their condition. Puppies, kittens, senior pets, and snub-nosed breeds are more at risk. Watch for these signs of dehydration in pets:
- Lethargy
- Loss of appetite
- Dry mouth/gums
- Dry nose
- Sunken eyes
- Decreased skin elasticity
- Excessive panting
- Lack of urine output
- Weakness
- Vomiting/diarrhea (severe cases)
- Fever or heatstroke (severe cases)
How Much Water Do Pets Need?
Different factors affect how much water pets need, including the amount of fluid in their pet food, their activity level, and environmental conditions such as temperature and humidity. We’ve provided some general guidance below for cats and dogs, but if you’re unsure if your pet is properly hydrated, consult your veterinarian.
Water Intake for Cats
A good rule of thumb is that cats should drink 3.5-4.5 ounces of water every day for every 5 pounds of body weight, meaning a 10-pound cat needs about 7-9 ounces of water daily. You can measure the amount of water in their bowl at the beginning and end of each day, or pull up the loose skin at the nape of your kitty’s neck. If it springs back into place, your cat is hydrated.
Water Intake for Dogs
Dogs tend to need more water on a daily basis than cats. The recommended daily water intake for dogs is one ounce for every pound of body weight, meaning a 20-pound dog needs 20 ounces of water every day. Gently pinch your pup’s skin near the shoulder blades and let go. If it returns to normal quickly, your dog is hydrated.
Keeping Pets Hydrated
Some pets naturally lap up enough water to meet their nutritional needs, while others need more coaxing. Try these tips to encourage your pets to drink:
- Use stainless steel or ceramic bowls, as these retain less odor.
- Clean the bowl daily and refill with fresh water.
- Place multiple water bowls throughout your house.
- Consider a pet fountain.
- Try a different sized bowl, or one that’s elevated, or move the bowl to a different location.
- Add water to your pet’s food.
