Beach Day Checklist: Salt Water, Sand, and Sun Safety

A dog friendly beach on a sunny day is one of those things that reminds you why having a dog is so brilliant. The sheer joy of watching them sprint at the waves, dig enormous holes in the sand, and shake themselves dry all over you is hard to beat.

But the coast comes with a handful of health risks that are genuinely worth knowing about before you go. Some of them are subtle, some are serious, and most are entirely preventable with a bit of knowledge and a bit of preparation. This is your complete guide to a safer beach day.

Most dog owners know not to let their dog drink seawater in large amounts. What is less well understood is how little it actually takes to cause a problem, and how fast that problem can develop.

Seawater is roughly three times saltier than a dog's blood. When a dog swallows it, even in small amounts during play or fetching, the body's response is to pull water out of the cells and into the gut to try to dilute the salt. This has two effects that work against each other: the dog becomes thirsty and dehydrated, and the gut fills with fluid, which typically results in diarrhoea. That diarrhoea causes further dehydration. Things can escalate quickly, particularly on a hot day when the dog is already losing water through panting.

In larger amounts, saltwater can cause sodium toxicity, also known as salt poisoning. This is a medical emergency. Symptoms include vomiting and diarrhoea, extreme thirst, lethargy, muscle tremors, wobbling, and in severe cases, seizures and loss of consciousness.

What to do:

• Bring more fresh water than you think you will need and offer it regularly throughout the day, at least every 30 minutes

• If your dog has been drinking seawater and is sick, vomiting, or acting strangely, do not give large amounts of fresh water at once as this can worsen the sodium imbalance. Offer small amounts frequently and contact your vet

• Signs of mild saltwater ingestion (loose stools, brief lethargy) often resolve at home with rest and fresh water. Signs of sodium toxicity require immediate vet attention

This one catches a lot of owners off guard because it does not feel like an obvious danger.

Sand impaction happens when a dog swallows enough sand to cause a blockage in the digestive tract. It sounds extreme, but it is more common than most people realise, particularly in dogs that love to fetch. Here is why.

A wet tennis ball thrown onto a sandy beach picks up a coating of sand every time it lands. Your dog then picks it up with their mouth, and with every grip, squeeze, and carry, they ingest a small amount of sand. Add a few hours of enthusiastic fetching, some digging and sniffing, and a dog that mouths at the sand while playing, and the cumulative amount swallowed can become significant.

Sand is dense and does not digest. In large enough quantities, it sits in the intestine, absorbs water, compacts, and can cause a partial or complete blockage.

Symptoms of sand impaction to watch for in the hours and days after a beach visit:

• Vomiting, particularly if it continues for more than a few hours

• Straining to pass stools or producing very little stool despite trying

• A bloated, hard, or tender-feeling stomach

• Sudden lethargy or reluctance to eat

• General signs of discomfort such as restlessness, hunching, or whimpering

If you notice any of these, contact your vet. Sand impaction can require veterinary treatment to resolve.

What to do:

• Swap the tennis ball for a solid rubber ball or a ball with less surface texture that does not hold as much sand

• Rinse toys regularly during play to reduce the sand coating

• Discourage digging and mouthing at dry sand where possible

• Limit the overall length of beach sessions for very enthusiastic diggers and fetchers

Yes, they absolutely can, and it is more common and more serious than many owners realise.

Dogs with thick, dark coats over their backs are relatively well protected. But several areas on most dogs are genuinely vulnerable to UV damage:

The nose. Pink or lightly pigmented noses are the most commonly sunburnt part of a dog. Repeated sunburn on the nose can cause the skin to become cracked, sore, and in the longer term, increases the risk of skin cancer in that area.

The ears. The tips of the ears, particularly on dogs with short or light fur there, are exposed to direct sun and can burn. This is especially common in dogs with white or cream-coloured coats, and in breeds like bull terriers, Dalmatians, and whippets.

The belly. Dogs that lie on their backs in the sun, or that spend time paddling in shallow water with their bellies exposed, can burn on the skin of the abdomen where fur coverage is thinnest.

Parted fur lines. Any area where the coat naturally parts or is thinner than usual can be vulnerable.

Signs of sunburn in dogs look similar to sunburn in humans: the skin appears pink or red, feels warm or tender, and the dog may flinch if you touch it. In more severe cases, blistering and peeling can occur.

What to do:

• Apply a pet-safe, fragrance-free sun cream (SPF 30 or above) to vulnerable areas before sun exposure. Never use human sun cream without checking it is pet-safe as many contain zinc oxide, which is toxic to dogs if licked

• Keep vulnerable dogs out of direct sun during the hottest part of the day, typically 11am to 3pm

• Seek shade regularly throughout the day

• If your dog is sunburnt, keep the area out of the sun and contact your vet if the skin is blistered, very painful, or covers a large area

Even on a well-managed beach day, your dog's body has been through a lot. Heat, exertion, salt exposure, and the general sensory overload of a big outing can leave them tired and their digestion working overtime.

Getting fluid back into a dog after a hot, active day sounds straightforward, but some dogs are reluctant to drink plain water when they are tired or their stomach is unsettled. This is where both of these products earn their place.

Beef Bone Broth Powder mixed with warm water creates a savoury, deeply palatable broth that most dogs will drink eagerly even when they are off plain water. It is also packed with collagen, glucosamine, and amino acids, which support the gut lining, joints, and overall recovery after an active day. Mix one teaspoon of powder with 100ml of warm water, stir until smooth, and offer it alongside or instead of their usual water bowl post beach.

Goats Milk Powder is a gentle, highly palatable hydration option that is particularly good for dogs with sensitive stomachs. It is naturally lower in lactose than cow's milk and contains natural prebiotics that support gut health at the same time as encouraging the dog to drink. Made up with water and offered as a drink, it is one of the most effective ways to get a reluctant drinker to take on fluids after a tiring day.

Both can be made up and offered that evening or the following morning as part of the recovery routine. Used together, they offer a great combination of palatability, hydration, and nutritional support after a demanding summer outing.

Most beach related digestive upsets are mild and resolve within 24 hours with rest, fresh water, and Super Tummy Instant. But contact your vet promptly if:

• Vomiting or diarrhoea continues for more than 24 hours or is severe

• Your dog is very lethargic, cannot stand, or is trembling

• You suspect significant sand ingestion and their stomach looks bloated or feels hard

• Your dog drank a large amount of seawater

• There is blood in their vomit or stools

• Symptoms of sunburn are severe, blistered, or covering a large area

When in doubt, a phone call to your vet is always the right move.

A beach day with your dog is one of summer's great pleasures. It does not need to come with anxiety, just a little preparation. Know the risks, pack the right things, watch your dog around the waves and the sand, and have a plan for when you get home.
