How to Keep Pets Cool and Hydrated in the Desert Heat
Arizona summers are no joke—and our pets feel the heat just as much as we do. Whether they’re snoozing indoors or playing outside, hydration plays a critical role in keeping your dog or cat healthy, happy, and safe. In extreme heat, even a short walk or skipped water bowl refill can lead to dehydration, which affects temperature regulation, digestion, and organ function.
In this guide, we’ll walk through how much water pets need, how to hydrate a dog or cat that’s sick or avoiding fluids, and how to spot early signs of dehydration before they become serious. If you live in a hot, dry climate like Arizona, a few proactive steps can go a long way toward protecting your furry family members.
How Much Water Does a Dog or Cat Need Each Day?
Pet hydration needs vary based on weight, activity level, and time spent in the heat.
Dogs generally need about 1 ounce of water per pound of body weight per day. That means a 50-pound dog should drink around 50 ounces daily—more if they’ve been active or are recovering from illness.
Cats typically require 5 to 10 ounces of water per day, depending on size, age, and diet. Cats that eat primarily dry food may need more water than those on wet food.
If your pet is spending time outside, even in shaded areas, they’re losing more water than you may think. Be especially mindful during Arizona’s hottest months (June–September).
Signs of Dehydration in Pets
-
Dry or sticky gums
-
Sunken eyes
-
Lethargy or weakness
-
Panting (dogs) or faster-than-normal breathing (cats)
-
Skin tenting (pinch the skin at the back of the neck—if it stays “tented,” they may be dehydrated)
How to Hydrate a Dog or Cat That’s Sick or Won’t Drink
Some pets don’t drink enough on their own—especially if they’re ill, recovering, or elderly. Here are tips to support hydration safely:
For Pets with Vomiting or Diarrhea:
-
Offer small sips of cool water or vet-approved electrolyte solutions
-
Never force fluids—encourage but don’t overwhelm
-
In cases of severe vomiting or parvo, fluids under veterinary supervision are essential
For Pets That Refuse to Drink:
-
Try unsalted chicken broth (without onion or garlic)
-
Add water to dry kibble or offer wet food
-
Offer ice chips or gently syringe/dropper water (ask your vet first)
-
Senior pets may need reminders—place extra water bowls or guide them to drink
If your pet refuses fluids or symptoms worsen, don’t wait—call your veterinarian immediately. Hydration is critical to recovery and survival, especially in Arizona’s heat.

Hydration Tips for Arizona Summers
Desert life requires year-round hydration awareness, but summer brings extra challenges. Here’s how to support healthy hydration in every season:
-
Offer multiple water sources in shaded, cool areas
-
Use pet-safe fountains to encourage drinking, especially for cats
-
Keep indoor temperatures cool and use fans or AC to reduce water loss through panting
-
Bring water and a bowl when traveling or exercising with pets
-
Watch for behavioral changes—decreased urination or excessive panting may be early signs of dehydration
Final Thoughts: Monitor, Adjust, and Ask Your Vet
Hydration is one of the simplest ways to safeguard your pet’s health in the Arizona heat. But every pet is different—age, health conditions, medications, and environment can all affect their water needs.
- Check your pet’s water bowl several times a day.
- Know what’s normal for your dog or cat—and notice changes early.
- When in doubt, call your vet.
