Start with the cottage, not the coastline

It is tempting to pick a stretch of coast first and worry about the accommodation afterwards, but with a dog in tow the order matters. A cottage with a generous garden and a five-minute walk to the sand is worth far more than a prettier village where you will be forever clipping on the lead. Before you book, read the listing as though you were a suspicious border collie. "Enclosed garden" can mean anything from six-foot stone walls to a low picket fence with a gap behind the shed. Ask for photographs of the boundaries, not just the patio. Ask whether the gate latches properly, whether the garden backs onto a road or a working farm, and whether there are neighbouring dogs. A quick email before booking saves a week of anxious supervising.

Think about the layout indoors too. Tiled or stone floors are a blessing after a wet walk, and a utility room or boot room gives you somewhere to strip off sandy harnesses before they meet the carpet. If your dog is elderly or nervous, a ground-floor bedroom avoids the staircase question entirely. And check the small print: many cottages accept one dog but charge for a second, and some quietly exclude certain breeds. Knowing the rules upfront means you can relax when you arrive.

Find the off-lead beaches before you go

The single biggest factor in a good coastal dog holiday is how much genuine off-lead running your dog gets. In the UK, beach access is rarely simple. Some stretches are dog-friendly all year, some ban dogs entirely between Easter and the end of September, and many operate a confusing patchwork where dogs are allowed on one half of the sand and not the other. Local council websites publish these seasonal orders, and they change more often than people expect, so check the rules for the exact dates of your trip rather than trusting an old forum post.

As a rule of thumb, the further you walk from the car park, the friendlier the rules become. Long, dune-backed beaches in Northumberland, Norfolk, Pembrokeshire and the Scottish coast often have vast areas where a dog can gallop without bothering anyone. Busy resort beaches in high summer are a different matter. If you are travelling in July or August, plan your beach time for early morning or after six in the evening, when the crowds thin and the light is lovelier anyway.

• Check seasonal dog bans for your exact travel dates, not just the beach name.
• Look for beaches with a slipway or ramp rather than steep steps, especially for older dogs.
• Note where the nearest bin is. Most owners pick up, but bins can be half a mile away.
• Identify a second, quieter beach as a backup for windy or crowded days.

Shingle, sand and the summer crowds

Not all beaches suit all dogs. Sand is soft and forgiving, but it gets hot underfoot on a sunny afternoon and clings to everything. Shingle is brilliant for a quick shake-and-go but brutal on paws and uncomfortable for dogs with thin pads or arthritis. If your dog is a sprinter, sand is usually the kinder surface. If your dog prefers a sniff-and-stroll, a shingle beach at low tide can be wonderful, as long as you keep the walks short and check the pads afterwards.

Summer shingle spots are the ones to avoid at peak times. The stones hold heat, the crowds are dense, and there is often nowhere shady to rest. A dog who is fine on a quiet February beach can become overwhelmed in August. Watch for signs of overheating: heavy panting that does not settle, a reluctance to walk on, or a wobbly gait. Flat-faced breeds struggle particularly in the heat, so keep their beach time brief and always carry water. Sea swimming is not automatically safe either, strong currents and steep shelving catch out confident dogs every year.

Dog-friendly pubs and the art of the evening meal

A good dog-friendly pub is the heart of a coastal holiday. The best ones do not just tolerate dogs; they put a water bowl by the door, keep a jar of biscuits behind the bar, and seat you somewhere with a bit of space rather than wedged between two tables. Ring ahead in summer. "Dog-friendly" often means the bar area only, and on a Friday night that area fills fast. Booking a table at five o'clock, before the rush, is the quiet trick that makes the whole evening work.

Choose pubs with wooden or stone floors over carpet, and a garden with a wall rather than an open field. If your dog is reactive or shy, a corner table facing the room lets them settle without being approached from behind. And do not overlook the simple option: fish and chips eaten on a bench overlooking the harbour, with the dog lying contentedly at your feet, is hard to beat.

Pack for sand, salt and wet paws

Coastal holidays punish poor packing. Bring more towels than you think you need, ideally old ones you do not mind ruining. A microfibre drying coat cuts drying time dramatically after a swim, and a shallow washing-up bowl in the boot makes rinsing sandy paws far easier than wrestling with a hosepipe. Pack a long line for beaches where recall is not yet reliable, a spare lead in case one gets lost to the sea, and a pet first-aid kit with a tick tool, as coastal grassland and dunes are tick territory.

Finally, plan the journey itself. Break a long drive every couple of hours, avoid leaving a dog in a parked car on even a mild day, and bring a familiar blanket so the cottage smells like home by bedtime. Do that, and the coast will feel less like a gamble and more like the holiday you both needed.
