Is this an Emergency? Quick assessment
Ask these questions now:
- Is the dog responsive? (eyes open, moves, or vocalizes)
- Is the dog breathing normally? (steady chest/abdominal rise and fall)
- Are the gums or tongue blue, gray, or very pale? (signs of poor oxygenation)
- Is the dog coughing, gagging, spluttering, or struggling to breathe?
Rescue safety (do not become a second victim)
- Use the ‘‘reach, throw, row, go’’ hierarchy: reach with a pole/paddle/branch, throw a flotation device, row to the victim, only go in the water as a last resort and only if trained.
- Encourage the dog onto a boat or flotation device—support the chest and hindquarters when lifting.
- Keep your own airway and footing; rescue situations commonly cause human injury and further animal injury.
Step-by-step first aid procedure after rescue
Follow these numbered steps in order. Work quickly but calmly.
1) Move to a safe, warm area and assess responsiveness
- Call the dog’s name and gently shake the body. If unresponsive, shout for help and prepare to begin CPR.
- Position: place the dog in lateral (side) recumbency with the head and neck in a neutral position. Tip the head slightly downward so water flows out of the mouth.
- If you can see large debris (sticks, large vomit pieces), remove it carefully with your fingers or a forceps—only if you can see it clearly. Do not perform blind finger sweeps; you may push material further into the airway.
- If you have suction (portable suction device), use it to remove fluid. Otherwise allow gravity to drain the mouth.
- Look, listen, and feel for breathing for no more than 10 seconds: look for chest rise, listen for breath sounds, and feel for air against your cheek.
- Check mucous membrane color: pink = better; blue/pale = severe hypoxia.
- If the dog is not breathing but has a heartbeat: give rescue breaths—one breath every 3-5 seconds (12–20 breaths/min). Use a face mask or cover nose and mouth—avoid mouth-to-snout unless necessary and you understand the technique. Each breath should make the chest rise visibly.
- If there is no heartbeat or you cannot detect a pulse, start CPR immediately. Veterinary CPR guidance (RECOVER/VECCS) recommends:
(References: RECOVER Veterinary CPR Guidelines; VECCS protocols)
5) Manage hypothermia and shock
- Cover with dry towels or blankets. If available, place a warm (not hot) heating pad under blankets or use warm packs—check skin frequently to avoid burns.
- Avoid rubbing the skin or extremities vigorously.
- Keep the dog flat and transport quickly.
- Even if the dog appears to recover fully, transport without delay for monitoring and diagnostics (oxygen, chest x-rays, bloodwork). Notify the clinic you are en route and that this is a drowning/near-drowning case.
Recognizing and explaining secondary drowning (delayed pulmonary edema)
What it is: Near-drowning may allow water into the lungs, which damages lung tissue and can trigger pulmonary edema (fluid accumulation) over hours to up to 72 hours. This is often called "secondary drowning" or delayed pulmonary edema.
Signs to watch for (may appear hours later):
- Coughing, especially productive or worsening cough
- Increased respiratory rate or effort, open-mouth breathing
- Lethargy, weakness, collapse
- Pale, gray, or blue gums
- Gurgling lung sounds, crackles, or wheezes
- Refusal to eat, ongoing vomiting
(Source: VECCS, veterinary emergency textbooks)
What NOT to do (common dangerous mistakes)
- Do not go into dangerous water if you are not trained. Many would-be rescuers drown trying to save pets.
- Do not perform blind finger sweeps of the mouth or pharynx—this can push material further into the airway.
- Do not give large volumes of water or induce vomiting—this may worsen aspiration.
- Do not delay transport. Even seemingly minor cases can progress to severe pulmonary edema.
- Do not use direct mouth-to-snout rescue breathing without a barrier if you can avoid it; use a pocket mask if available.
- Do not apply direct heat (hot water bottles, heating pads directly against skin) without a barrier; warm slowly.
When to Rush to the Vet — clear criteria
Get emergency veterinary care immediately if any of these are present after a water incident:
- Unresponsive, not breathing, or absent heartbeat (start CPR and call emergency vet)
- Gasping, severe difficulty breathing, or persistent open-mouth breathing
- Blue, gray, or very pale mucous membranes
- Continuous coughing, especially productive or bloody
- Collapse, seizures, or disorientation
- Ongoing vomiting, inability to keep down water/food
- Signs of hypothermia (shivering, low body temperature, very weak)
At the veterinary clinic: what to expect
Veterinarians will typically:
- Provide oxygen therapy and continuous monitoring
- Take chest radiographs (x-rays) to look for aspiration or pulmonary edema
- Administer IV fluids, warmed fluids if hypothermic
- Provide bronchodilators, diuretics, or antibiotics as indicated
- Admit for monitoring if respiratory compromise is possible
Prevention
- Supervise dogs around open water at all times. Keep them on a leash if near fast water or unfamiliar shorelines.
- Use canine life jackets for boating, surfing, or inexperienced swimmers—ensure proper fit.
- Teach dogs to exit points (steps, ramps) in pools and docks; mark safe exit areas.
- Keep pool covers secured and gates locked; teach children and visitors water safety too.
- Avoid allowing dogs to swim alone or in dangerous currents, cold water, or at night.
- Know basic pet CPR and consider water-rescue training for people in high-risk situations.
Key Takeaways
- Prioritize human safety first—use reach/throw/row before going into the water.
- If a dog is unresponsive or not breathing, begin CPR immediately and transport to an emergency vet.
- Never assume a recovered dog is safe—secondary drowning (delayed pulmonary edema) can develop hours later. Immediate veterinary evaluation is essential for all drowning/near-drowning cases.
- Do not perform blind finger sweeps, do not induce vomiting, and do not delay seeking professional care.
If you are in doubt at any point, call your regular veterinarian or nearest emergency animal hospital and tell them you have a drowning/near-drowning patient. Emergency numbers again: ASPCA Poison Control (888) 426-4435 | Pet Poison Helpline (855) 764-7661
Always follow up with a veterinarian—home care is not a substitute for professional medical evaluation and treatment.
Frequently Asked Questions
How long after a near-drowning can my dog develop problems?
Problems can appear immediately or be delayed for hours to 72 hours after the event. Pulmonary inflammation and edema (secondary drowning) often develop within 24–72 hours. Any dog rescued from water needs prompt veterinary evaluation and monitoring.
Can I perform mouth-to-snout CPR if I don't have a mask?
Yes—if no barrier is available, mouth-to-snout rescue breaths are acceptable in an emergency, but use caution and only if necessary. A mask or barrier reduces infection risk and improves ventilation. Try to use a pocket mask or a cloth barrier if possible.
My dog coughed and seems fine—do I still need to see a vet?
Yes. Even mild or transient coughing can precede worsening respiratory distress. Veterinary evaluation (oxygen, chest x-rays, monitoring) is recommended for all near-drowning cases.
What if my dog inhaled saltwater or chlorinated pool water?
Both saltwater and pool water can irritate the lungs and lead to aspiration-related inflammation or infection. Veterinary assessment is still required; treatment may include oxygen, supportive care, and sometimes antibiotics.
