Saltwater poisoning in dogs: Symptoms to look out for

Many dog owners enjoy spending time at the beach, allowing their furry friends to frolic in the waves and enjoy the sun. While the beach can be a fun and refreshing experience, it’s important to be aware of the potential dangers, including saltwater poisoning. If your dog ingests saltwater, it can lead to significant health issues if not addressed promptly. At Peak Vets, we explore the symptoms of saltwater poisoning in dogs to help you recognize the signs and take appropriate action to protect your canine companion’s well-being.

What makes salt poisonous to dogs?

When your dog ingests salt, it causes the cells in their body to release water. If your dog only ingests a small amount of saltwater, is hydrated and has access to plenty of fresh water, it’s unlikely to cause any problems.

However, if your dog ingests a large amount of saltwater, is already dehydrated, and doesn’t have access to fresh water, this can cause their cells to release too much water. This can be fatal if not treated promptly.

If you have any immediate concerns, get in touch with Peak Vets in Sheffield today.

Excessive thirst

A common symptom of saltwater poisoning in dogs is excessive thirst. After ingesting saltwater, dogs may feel dehydrated and attempt to quench their thirst by drinking more water than usual. Monitor your dog’s water consumption, and if you notice a significant increase, it could be a warning sign of saltwater poisoning.

Vomiting and diarrhoea

Saltwater ingestion can irritate your dog’s tummy, leading to vomiting and diarrhoea. If you see your dog vomiting or experiencing loose stools after a beach outing, you should seek veterinary attention promptly. These symptoms can quickly lead to dehydration, electrolyte imbalances, and further complications if left untreated.

Lethargy and weakness

Dogs suffering from saltwater poisoning may appear tired, weak, lacking in energy, and be reluctant to engage in their usual activities. Keep an eye out for unusual fatigue in your dog, as it could be a sign of saltwater poisoning.

Excessive drooling

An excessive amount of drooling is another potential symptom of saltwater poisoning. If you notice your dog drooling more than usual, with saliva appearing thicker or frothy, it could indicate irritation of the mouth and throat caused by saltwater. Contact your local vets in Sheffield to discuss your observations and seek appropriate guidance.

Tremors and seizures

In severe cases, saltwater poisoning can lead to neurological symptoms, including tremors and seizures. These symptoms indicate a more advanced stage of poisoning and require immediate veterinary attention. If your dog experiences seizures or uncontrollable shaking, it is crucial to seek emergency veterinary care without delay.
