Have you ever wondered whether your furry friend is drinking enough water? It’s easy to assume everything is fine when you refill the bowl each day, but pets don’t always make thirst obvious. Your dog may still be eager for a walk, and your cat may still curl up in their favorite spot, even when they aren’t taking in as much water as they need.
July is National Pet Hydration Awareness Month, and it’s a great time to pay closer attention to the small changes that can reveal more about your pet’s daily water habits. After all, proper hydration is just as important for them as it is for you.
In this post, we’ll walk through seven hydration clues pet parents often miss, why water matters so much for your dog or cat, and simple ways to support healthy drinking at home. These signs can help you notice when something seems off, but they can’t diagnose dehydration on their own. If your pet seems unwell or has several changes at once, it’s always best to contact your vet.
Why Hydration Matters for Your Pet
Water supports nearly every part of your pet’s body. It helps regulate body temperature, move nutrients through the body, support digestion, lubricate joints, and keep organs working as they should. As dehydration develops, pets may feel unwell, especially during warm weather, after exercise, or when vomiting or diarrhea causes fluid loss.
Your pet’s water needs can also change from day to day. Dogs may lose more fluid through panting during walks, playtime, or hot afternoons. Cats can be more subtle, especially because they may get a meaningful share of their daily water from food, particularly when they eat wet meals. Pets that eat mostly dry food may also rely more heavily on their water bowl than pets that eat wet food or moisture-rich meals.
At CocoTherapy, we believe one of the best things you can do is learn what’s normal for your individual pet. You don’t need to keep track of every sip, but knowing their usual appetite, energy level, potty habits, and drinking routine can make it much easier to notice when a real change is happening.
7 Hydration Clues You May Be Missing
One hydration clue on its own doesn’t always mean your pet is dehydrated. A warm day, a long car ride, or an extra-active afternoon can all affect how much your pet drinks. However, when several changes appear together, it may be time to take a closer look.
Here are a few clues to watch out for:
1) Dry Or Tacky Gums
Your pet’s gums can offer a helpful clue about hydration. Healthy gums usually feel moist and smooth, not dry, sticky, or tacky. You can gently lift your pet’s lip and touch the gums with a clean finger to get a sense of what feels normal for them.
Dry gums may happen when your pet isn’t taking in enough fluids or is losing fluids through panting, vomiting, or diarrhea. These changes are more concerning when they appear alongside low energy, appetite changes, or digestive upset.
It’s a good idea to check your pet’s gums occasionally when they’re feeling well. That way, you’ll have a better idea of what’s normal for them if something changes later.
2) Skin That Stays “Tented”
You may have heard of the skin-tent check. This involves gently lifting a small fold of loose skin, usually around the shoulder blades, then letting it go. In a well-hydrated pet, the skin should usually return to its normal position quickly.
If the skin seems to stay raised or returns more slowly than usual, it can be one hydration clue to keep in mind. However, it’s important to remember that this test isn’t perfect. Skin elasticity can vary depending on your pet’s age, body condition, and skin health, so it’s best to look at this sign along with other changes.
For example, a senior pet or a very thin pet may naturally have skin that doesn’t bounce back as quickly. That’s why it’s more useful as part of the bigger picture than as a stand-alone test.
3) Dull Or Sunken-Looking Eyes
Your pet’s eyes should normally look bright, moist, and comfortable. When dehydration becomes more serious, the eyes may look less bright than usual, slightly dull, or more deeply set in the eye sockets.
You may also notice that the area around the eyes looks less full than usual. Eye changes are worth taking seriously, especially if your pet also seems weak, quiet, or reluctant to move around.
Sunken-looking eyes can be a sign of more significant fluid loss, so this isn’t something to watch at home for too long. Contact your vet if you notice this change, particularly if it appears with vomiting, diarrhea, or unusual tiredness.
4) Lower Energy Than Usual
Every pet has an occasional lazy day. Your dog may be tired after a long hike, or your cat may decide that the couch is the only acceptable place to spend the afternoon. But if your furry family member suddenly seems much less interested in the routines they usually enjoy, it’s worth paying attention.
Maybe your dog doesn’t greet you at the door like they normally do. Maybe your cat is hiding more often, skipping playtime, or avoiding their favorite perch. Low energy can happen for many reasons, including dehydration, illness, pain, stress, or changes in routine.
The key is to look at the full pattern. If your pet seems tired and is also drinking less, eating less, panting more, or having digestive issues, that combination gives you a stronger reason to check in with your vet.
5) A Sudden Drop in Appetite
Most pets are pretty clear about when they want to eat. That’s why a sudden lack of interest in food can be an important change to notice, especially if it comes with reduced drinking or signs of stomach upset.
A skipped meal doesn’t always mean something is wrong. Some pets can be picky, and a busy day or minor routine change can sometimes affect appetite. Still, if your pet turns down food repeatedly, only accepts treats, or seems uninterested in meals they usually love, it’s worth taking seriously.
Dehydration can affect appetite, but appetite changes can also point to many other health concerns. If your pet isn’t eating and also seems weak, has dry gums, vomits, or has diarrhea, it’s best to call your veterinarian rather than waiting for things to improve on their own.
6) Changes In Potty Habits
Your pet’s bathroom habits can tell you a lot about their overall wellness. For dogs, you may notice fewer potty breaks, smaller amounts of urine, or urine that looks darker than usual. For cats, you may notice smaller litter box clumps, repeated trips to the box, straining, or a litter box that doesn’t seem to need cleaning as often.
It’s just as important to notice the opposite pattern. A pet that suddenly drinks and urinates much more than normal may be dealing with something other than simple thirst. Changes in thirst and urination can be connected to health conditions, medications, and diet changes, so it’s best not to limit water access.
Instead, make a note of when the change started and what else you’re noticing. You should contact your vet if the change is sudden, significant, persistent, or paired with other symptoms. If your cat is producing very little or no urine, seems to be straining, or appears distressed in the litter box, seek veterinary care right away.
7) More Panting, Vomiting, Or Diarrhea
Panting is normal for dogs after activity or during warm weather, but heavy panting can increase fluid loss. That’s why it’s important to offer water during walks, outdoor play, car rides, and warm afternoons. Regular water breaks can make a difference, especially during active outings or warm weather.
Vomiting and diarrhea can also lead to dehydration quickly because your pet is losing fluids faster than they can replace them. Puppies, kittens, senior pets, and small dogs can become dehydrated more quickly than healthy adult pets, so even a short period of stomach upset deserves extra attention.
If your pet vomits repeatedly, has severe diarrhea, can’t keep water down, or seems weak and uncomfortable, contact your veterinarian as soon as possible. These can be signs that your pet needs more support than you can safely provide at home.
Quick Tips for Helping Your Pet Stay Hydrated
Healthy hydration doesn’t need to be complicated. A few simple habits can make water easier to access, more appealing to drink, and easier for you to monitor. The goal is to create a routine that gives your pet plenty of easy opportunities to stay hydrated, not to force them to drink more than they need.
Here are a few quick tips for encouraging your pet to drink more water:
- Refresh water often. Empty, rinse, and refill your pet’s water bowl at least once a day. Fresh water is often more appealing, especially if your pet is picky about taste or smell. Daily cleaning also helps prevent residue and slimy buildup from forming inside the bowl.
- Offer more than one bowl. Place water bowls in several easy-to-reach areas, especially if you have a larger home, multiple pets, or a pet that spends time on different floors. Cats may also prefer a quiet water station away from busy rooms, loud appliances, or their litter box.
- Bring water along. Keep a portable bowl and fresh water with you for walks, car rides, beach days, and outdoor activities. Your pet may be more active than usual when you’re away from home, and regular water breaks can help them stay comfortable.
- Add moisture to meals carefully. Ask your vet whether adding a small amount of water to meals or including appropriate wet food could be a good fit for your pet. This can be especially helpful for pets that eat mostly dry food or don’t seem very interested in drinking from a bowl.
- Try a different water setup. Some pets prefer wide ceramic bowls, stainless steel bowls, or gently moving water from a pet fountain. For more ideas, read our guide to simple ways to make sure your pet gets enough water.
Could a Few Simple Water Habits Make a Difference?
Can you really boost your pet's hydration with a few easy changes? Absolutely, especially when you keep their routine simple and consistent. Fresh water, clean bowls, convenient water stations, and a little extra attention during warm weather can all support healthy hydration habits over time.
The most important thing is staying familiar with what’s normal for your pet. If you notice signs like dry gums, sunken eyes, weakness, vomiting, diarrhea, or sudden changes in drinking and urination, don’t wait too long to ask for veterinary advice. Knowing when a pet health change may be an emergency can help you act quickly when your furry friend needs extra care.
