Signs of Dehydration in Dogs (and What to Do on the Go)
Water supports your dog’s vital organs, so noticing signs of dehydration early on could save their life. Dehydration symptoms can escalate quickly during walks, hikes, and day trips, especially when warm weather or vigorous exercise is involved. Monitoring your dog’s behaviours closely during outdoor activities is the best way to keep them safe.
Familiarise yourself with common signs of dehydration so you can act fast in an emergency. The following information offers general tips only, not veterinary advice. If you have concerns about your dog’s health, please consult your veterinarian right away.
Common Signs of Dehydration
Dehydration occurs if your dog’s body is losing more fluids than it’s taking in. Without enough fluids in your dog’s body, essential organ function could be disrupted. If your dog is experiencing dehydration, they may display the following:
-
Excessive panting
-
Dry or sticky gums
-
Lethargy or reduced energy
-
Sunken eyes
-
Loss of skin elasticity
What to Do on the Go
If you notice your dog displaying any of the following symptoms, especially when exercising in hot weather, immediately stop the activity and follow these steps:
-
Bring your dog to a cool, shaded spot
-
Offer small amounts of fresh, clean water (drinking too much too quickly could cause vomiting)
-
Give your dog time to rest before continuing your activity
-
If your dog's symptoms don’t improve, end the outing
When to Seek Veterinary Care
Some dogs return to normal after resting and drinking some water, but cautiously observe your dog’s behaviour while they’re resting to ensure they’re okay. If your dog’s symptoms worsen or don’t improve, contact a veterinarian.
Dogs with worsening symptoms may vomit, collapse, or appear confused. Worsening symptoms could be a sign of heatstroke or severe dehydration, which requires immediate veterinary advice. If you aren’t near home, contact the closest vet in the event of an emergency.
How to Help Prevent Dehydration
No one expects to deal with dog dehydration, but it’s always better to be safe than sorry. Here are some ways to ensure your dog stays safe and healthy during your outings:
-
Bring plenty of water on every outing
-
Bring a dog water bottle or collapsible dog bowl to easily offer water
-
Have regular water breaks, even if your dog doesn’t seem thirsty
-
Take walks during cooler parts of the day when possible
-
When travelling, have the number of a local vet saved in your phone
Keep Your Dog Safe from Dehydration
Dehydration in dogs can escalate quickly and become devastating if not properly managed. To avoid the health concerns associated with dehydration, always keep an eye out for symptoms while exercising with your dog. As soon as their behaviours seem off, offer them water and let them rest until they improve.
Plan ahead by carrying water with you on long walks and regularly stop to offer water. All the advice above can help with general information about dog dehydration, but please consult a vet for expert advice if your dog shows signs of dehydration or illness when you’re on the go.
