If water gets into your dog's lungs, take them to the emergency vet immediately. Do not wait for your dog's symptoms to get worse, as dogs who are unconscious upon arrival at the vet will not have a good prognosis. Your pooch will need chest X-rays to evaluate the amount of water in the lungs. They will also need antibiotics to prevent pneumonia. These are treatments that cannot be given at home. Do not be tempted to perform the Heimlich maneuver on your dog. This technique is only recommended when a dog's airway is blocked by a solid material. Abdominal thrusts can cause vomiting and aspiration of stomach contents, which can cause further damage to the lungs. To reduce your pooch's risk of dry drowning, monitor them closely during playtime in the water. Additionally, you could fit them with a lifejacket to ensure their head stays above the water. Most importantly, be aware of the signs of drowning in dogs, and know your closest vet's location in case of emergency.
