Watching a dog run along the shoreline, leap over the waves or splash in the water is the perfect summer image. But the beach is not a neutral environment for dogs: salt water, the extreme heat of the sand, jellyfish, restrictive regulations and the risk of overheating make this an environment that requires preparation.
With the right information, going to the beach with your dog can be one of the best summer experiences for both of you.
Where are dogs allowed on the beach?
Regulations vary by municipality. In general, main beaches are off-limits to dogs during the high season (June to September). However, more and more municipalities are designating specific areas for dogs or allowing access outside bathing hours (before 9am or after 8pm).
Before going, look for information on the local council website or on sites specialising in dog-friendly beaches in Spain. Taking your dog to a prohibited beach can result in a significant fine.
Risks of sea water for dogs
Ingested salt water
Sea water is toxic to dogs in large quantities. Excess salt causes hypernatraemia (excess sodium in the blood), which manifests as vomiting, diarrhoea, lethargy, tremors and, in severe cases, seizures or kidney damage.
Dogs playing in the sea often swallow water without realising it, especially when chasing waves or retrieving objects from the water. Limit swimming time and always offer fresh water when coming out. If your dog vomits or has diarrhoea after the beach, consult your vet.
Jellyfish
Jellyfish washed up on the shore can sting dogs if they sniff, lick or step on them. Signs of a sting include swelling, redness, pain and, in severe cases, an allergic reaction. If your dog comes into contact with a jellyfish, move them away, clean the area with sea water (never with fresh water or by rubbing), and consult your vet if there is severe swelling or the dog appears to be in shock.
Currents and dangerous swimming areas
Not all dogs are good swimmers, and some overestimate their abilities. Avoid areas with strong currents, undertow or heavy surf. Overweight dogs, brachycephalic breeds and dogs with joint problems are at greater risk in the water.
Hot sand: an invisible danger
Beach sand can reach temperatures above 60°C in the height of summer. A dog's paw pads can burn in seconds if you walk on sand during the middle of the day.
Solution: go to the beach early in the morning or at sunset, when the sand is cool. If this isn't possible, look for shaded areas or wet the sand before letting your dog walk on it.
Sun and overheating at the beach
The combination of direct sun, glare off the water and hot sand makes the beach one of the highest-risk environments for heatstroke. Dogs should not be in direct sun without shade for more than 20–30 consecutive minutes in summer.
- Bring a parasol or small tent to create shade.
- Wet your dog periodically with fresh water.
- Let them rest in the shade with fresh water every 20–30 minutes.
- If you see excessive panting, heavy drooling or lethargy, leave the beach immediately.
Post-beach care
- Rinse your dog thoroughly with fresh water: salt and sand irritate the skin and coat.
- Clean the ears well: salt water can cause ear infections in dogs prone to otitis.
- Check the paw pads: for abrasions, shell cuts or irritation.
- Offer fresh water before food when you get home: hydration is the priority.
- If your dog ingested a lot of sea water (vomiting, diarrhoea, lethargy), visit the vet.
Nutrition before and after the beach
Don't feed your dog immediately before going to the beach or straight after returning if they've been very active. A full stomach increases the risk of gastric torsion in large breeds. Wait at least one hour.
At OnlyFresh you will find nutrition options from brands such as Harper and Bone, Amanova and TrovetPlus that combine high digestibility with quality natural ingredients, ideal for active dogs who make the most of summer.
