If your dog refuses to drink, the quickest fix is to add flavor to their water—like low-sodium chicken broth or the juice from a can of tuna. You can also switch to wet food, which is 80% water. However, if your dog hasn’t drunk any water for 24 hours or has dry, tacky gums, this is a medical emergency. You need to see a vet immediately.
Key Takeaways
- The “Tuna Water” Hack: A splash of tuna juice (from water-packed tuna) turns boring water into a high-value treat.
- The Ice Cube Trick: Many dogs love crunching on ice cubes, especially on hot days. It counts as hydration!
- The “Tacky” Test: If your dog’s gums feel sticky (like flypaper) instead of slick, they are significantly dehydrated.
- Fountains Work: Running water appeals to a dog’s instinct that “moving water = fresh water.”
The Vet’s Take: Max’s “Protest”
Last summer, Seattle hit a record high temperature. Naturally, I panicked about my Beagle-Lab, Max, staying hydrated. I filled his bowl with fresh, cool water… and he ignored it.
He sat there panting, looking at the bowl like it was filled with vinegar. It turned out, I had switched from tap water to “filtered” water because I thought I was being a good mom. Max, being a creature of habit (and stubbornness), hated the lack of “flavor” (chlorine/minerals) he was used to.
I learned a valuable lesson that day: You can lead a dog to water, but sometimes you have to trick them into drinking it.
The Science: Why They Stop Drinking
Dogs are usually good at self-regulating, so when they stop drinking, there is always a reason.
1. The “Mouth Pain” Factor
This is common in seniors or small breeds (Yorkies, Poms). If they have a cracked tooth or gum disease, lapping up cold water can cause a sharp jolt of pain.
- Vet Tip: Check their mouth. If they recoil when you touch their snout, it’s dental pain.
2. Nausea (The Vicious Cycle)
When a dog feels nauseous (from kidney issues or just an upset stomach), the thought of water makes them sick. But dehydration makes nausea worse.
- The Sign: They walk up to the bowl, hang their head over it, maybe sniff it, and then turn away.
3. The “Kibble” Effect
Dogs on dry kibble need significantly more water than dogs on wet food. Wet food is 70-80% water. If you recently switched to canned food, your dog might just not be thirsty because they are “eating” their water.
7 Vet-Approved Tricks to Boost Hydration
1. The “Dirty Water” Effect (Broth)
Dogs love “dirty” water. Adding a splash of Low-Sodium Chicken Broth or Bone Broth makes the water smell like meat.
- Warning: Ensure the broth has NO Onion or Garlic listed in the ingredients.
2. The Ice Cube Game
Max thinks ice cubes are treats. I toss three or four on the floor, and he crunches them up. It’s a great way to sneak in an extra ounce of water without them realizing it.
3. “Soup” Their Dinner
Add warm water to their dry kibble. Let it sit for 5 minutes until it makes a gravy.
- Benefit: Not only does this hydrate them, but it also releases the aroma of the food, enticing picky eaters.
4. The Pet Fountain
In the wild, standing water often means bacteria. Running water means fresh. A Pet Fountain ($30-$40) taps into this instinct. Many cats and dogs prefer drinking from a moving stream (or the toilet… don’t let them do that).
5. Fruit “Slushies”
Blend water with a few dog-safe fruits like Watermelon (seedless) or Blueberries. Pour it into a bowl as a “smoothie.”
- Avoid: Grapes, Raisins, or Cherries (Toxic).
6. Multiple Water Stations
If you have a two-story house, put a bowl on every floor. Laziness is real. Sometimes a dog just doesn’t want to walk downstairs to get a drink.
7. Bait the Bowl
Drop a few blueberries or a piece of chicken into the water bowl. They have to drink the water to fish out the snack. Bobbing for apples, doggy style!

Frequently Asked Questions
Q: Can I give my dog Gatorade? A: Generally, no. Regular Gatorade has too much sugar. If your vet recommends electrolytes, use Pedialyte (Unflavored) or a specific canine electrolyte powder. Sugar feeds bacteria in the gut and can make diarrhea worse.
Q: How much water should my dog drink daily? A: The general rule is 1 ounce per pound of body weight.
- Example: A 50lb Lab needs about 50oz (approx. 6 cups) of water a day.
Q: My dog drinks from the hose. Is that safe? A: Occasionally, yes. But be careful—hoses sitting in the sun can leach chemicals (phthalates) into the standing water inside the tube. Let the water run for a minute to flush it out before letting them drink.
