Salt water dogs are a unique breed that requires special care to thrive. They originated from ancient times when sailors would bring back dogs from their voyages and breed them with local dogs, resulting in a robust and resilient breed.
These dogs have a thick coat that sheds heavily, so regular grooming is essential to prevent matting and tangling. In fact, some salt water dogs shed so much that they require daily brushing to prevent hair from getting everywhere.
Salt water dogs are highly energetic and need plenty of exercise to stay happy and healthy. They require at least 30 minutes of exercise per day, which can include running, swimming, or playing fetch.

Causes and Risks
Consuming salt water can be fatal for dogs, with a mortality rate higher than 50% if left untreated.
Dogs who ingest large amounts of salt water can experience diarrhea, vomiting, and dehydration due to the excess salt drawing water from the blood into the intestines.
The excess salt can also disrupt the fluid balance in a dog's body, leading to a range of serious health effects including seizures, loss of brain cells, and injury to the kidneys.
Is Sea Water Harmful to Dogs?
Sea water contains a lot of salt, which can be toxic to dogs if they drink too much.
Dogs can become dehydrated quickly if they consume excessive amounts of salt water, which can lead to serious health effects.
A dog's body will try to correct the imbalance by releasing water from their cells, causing symptoms like dizziness, lethargy, and confusion.
Cells inside the body release water to even out the high salt levels in their blood, which can result in your dog becoming dizzy, lethargic, and confused.
If your dog doesn't have access to lots of fresh water, symptoms can become worse, especially at the beach where water is often scarce.
Dogs with toxic levels of sodium in their systems have a mortality rate higher than 50%, regardless of treatment, making it a serious condition that requires immediate attention.
In severe cases, excessive salt consumption can lead to seizures, a loss of brain cells, injury to the kidneys, and severe dehydration.

If your dog has been drinking sea water, they might experience vomiting and diarrhea. Confusion and lethargy can also be symptoms, and in severe cases, seizures or even death can occur.
Some common symptoms include:
- Excessive urination
- Extreme thirst

- Lethargy
- Diarrhoea
- Vomiting
- Nausea

If you suspect your dog has ingested too much sea water, get them to the veterinarian as quickly as possible. Your vet will attempt to restore your dog's water and electrolyte balance to normal levels, which can take up to 2-3 days of hospitalization.
Prevention and Action
To keep your dog safe at the beach, make sure they always have access to fresh water. This is the best thing you can do to prevent saltwater poisoning.
Take a break away from the water every 15 minutes to help avoid salt poisoning. This simple trick can go a long way in keeping your furry friend safe.
If you notice your dog drinking ocean water, restrict their access and provide them with fresh water and shade. Keep an eye out for signs of toxicity.
If your dog has been drinking seawater, offer them fresh water every 30 minutes or so to rehydrate them. This can help lower the chances of them experiencing vomiting or diarrhea.
Most dogs will recover after drinking seawater, but it's essential to monitor your dog to make sure that nothing changes and no symptoms start to develop.
