How Dogs Go to the Toilet on a Boat: Practical Tips for Sailing Dogs

Dogs on boats look wonderful in photos.

A happy dog in the cockpit. A sunset. A little life jacket. Maybe one ear flying in the wind like a tiny pirate flag.

But before all that romantic boat-dog life, there is one very real question every owner eventually asks:

How do dogs go to the toilet on a boat?

It is not the most glamorous part of sailing with dogs, but it is one of the most important. Because once you leave the marina, your dog still has normal dog needs. And unfortunately, dogs do not read pilot books, tide tables, or marina rules before deciding it is time.

Some dogs learn to use a mat on deck. Some only go ashore. Some need training, patience, and several confused looks. Every dog is different, and every boat setup is different too.

So let’s look at the practical options for sailing dogs, from short day trips to longer passages.

Why Toilet Training Matters Before Sailing With Dogs

If you only take your dog on short marina trips or day sails, toilet planning may feel simple. You walk the dog before you leave, sail for a few hours, and return before there is a problem.

But cruising is different.

You may spend a full day at anchor. You may leave early in the morning. You may arrive late. The weather may change. The dinghy ride to shore may be wet, long, or impossible. You may be in a bay where landing a dog is not easy.

And on longer passages, going ashore is obviously not an option unless your dog has secretly learned to fly. Which would be impressive, but not very common.

That is why it helps to think about toilet training before you really need it. A dog who understands where to go on board is much easier to manage, especially in bad weather, at night, or during longer coastal trips.

It is not only about convenience. It is also about your dog’s comfort and health. Holding urine or stool for too long can be stressful and unhealthy. A clear toilet routine makes boat life calmer for everyone.

Including the humans, who are usually the ones standing there at 6 a.m. holding a lead, wearing a jacket over pyjamas, and questioning their life choices.

Option 1: Taking Your Dog Ashore

For many sailing dogs, the easiest toilet solution is still the simplest one: go ashore.

This works well when you are in a marina, tied to a town quay, or anchored close to a beach or safe landing spot. You take the dog by dinghy, walk them on land, clean up properly, and return to the boat.

Many dogs prefer this because it feels normal. They already understand grass, soil, paths, and trees. A piece of artificial grass on a moving deck may not immediately impress them.

Going ashore is usually best for:

• marina stays

• short coastal cruising

• calm anchorages

• dogs who refuse to use the boat

• older dogs with established habits

• puppies still learning routines

But it also has limits.

In some places, landing a dog is difficult or not allowed. Some beaches have seasonal dog restrictions. Some bays have rocks, steep shores, private land, protected areas, or no safe landing spot. In bad weather, dinghy trips can also become unpleasant or unsafe.

So even if your dog usually goes ashore, it is useful to have a backup plan for the boat.

A dog toilet plan is like a spare impeller. You hope you do not need it today, but you feel much better knowing it exists.

Option 2: Using a Pee Pad or Training Mat

Pee pads are often the first thing people try on board.

They are easy to buy, light, and simple to store. For small dogs or puppies, they can work well, especially if the dog already knows how to use them at home.

On a boat, you can place a pee pad in a consistent spot, such as:

• cockpit corner

• bathing platform

• side deck

• foredeck

• cockpit sole

• dedicated dog toilet tray

The key is consistency. Dogs learn through habit and smell. If you move the toilet place every day, your dog may politely decide that you have no idea what you are doing.

Pee pads can be helpful for:

• puppies

• small dogs

• nervous dogs

• emergency backup

• bad weather

• night-time use

The downside is that they can move in the wind, get wet, smell if not changed quickly, and create waste. On a sailboat, anything light and disposable also has a mysterious desire to fly away at the worst moment.

If you use pee pads, secure them well, change them often, and never let them blow into the sea.

Option 3: Artificial Grass on Deck

Artificial grass is one of the most popular solutions for dogs on boats.

Many owners use a small patch of fake grass placed inside a shallow tray. The tray catches urine, and the grass gives the dog something that feels more natural under their paws.

Some dogs accept this quickly. Others stand on it with the expression of someone being asked to sign a suspicious contract.

To make it work, try using the artificial grass before your trip. Place it at home, on a balcony, in a garden, or near the boat. Let your dog sniff it and get used to it. You can also transfer a little smell from a previous toilet area to help them understand what it is for.

A good boat dog toilet tray should be:

• stable

• non-slip

• easy to clean

• big enough for your dog

• low enough to step onto safely

• placed in the same spot each time

• secured so it cannot slide around

For male dogs, some owners add a small washable post or object, because many male dogs prefer to lift a leg. Boat life is already full of strange modifications; a dog toilet post is just another chapter.

Artificial grass is useful for:

• medium and small dogs

• longer cruising

• anchorages without easy shore access

• night use

• dogs who like a “grass-like” surface

The main challenge is cleaning. Artificial grass needs regular rinsing and drying, otherwise it can smell quickly, especially in hot weather.

Option 4: A Dedicated Deck Toilet Area

Some cruising dog owners train their dog to use a specific deck area without artificial grass.

This could be a washable mat, textured surface, rubber mat, or small tray placed in the same location every time. The aim is to teach the dog that this is their boat toilet spot.

This can work well, but it usually takes patience.

Dogs are creatures of routine. If your dog has spent years learning that toilet means “land,” they may not immediately accept that the new bathroom is next to a winch handle and a coiled mooring line.

Training is easiest if you start slowly:

1. Choose one toilet spot on the boat.

2. Use the same word or command every time.

3. Reward your dog when they use it.

4. Keep the area clean but not completely unfamiliar in smell.

5. Practise before long passages.

6. Stay calm if it takes time.

Never punish a dog for not understanding. They are not being difficult on purpose. They are trying to understand a very strange human idea: “Please go to the toilet on this floating platform.”

To be fair, from the dog’s point of view, it is a lot to ask.

What About Long Passages?

For long passages, your dog needs a reliable toilet option on board.

Even if your dog usually goes ashore, you cannot depend on land during overnight sails, long coastal passages, offshore trips, or bad weather delays. A trained onboard toilet area becomes much more important.

Before attempting longer passages with a dog, practise during shorter trips. Let your dog use the toilet area while the boat is still, then at anchor, then during calm sailing if possible.

Some dogs will avoid going while the boat moves. Others may wait too long because they are nervous or unsure. This is why training before a real passage matters.

For longer passages, plan:

• a safe toilet area

• non-slip access

• a harness or safety line if needed

• easy cleaning supplies

• fresh water for rinsing

• waste bags

• disinfectant suitable for boats

• patience

If conditions are rough, safety comes first. Do not encourage your dog to move around on deck in dangerous conditions. In bad weather, a cockpit-based toilet area may be safer than going forward.

This also connects with general safety planning. If you sail with a dog, it is worth reading our guide to how to keep a dog safe on a sailboat, because toilet routines and safety routines often overlap more than people expect.

How to Train a Dog to Use the Boat Toilet

Training a dog to use a boat toilet is mostly about patience, repetition, and timing.

Start before you leave for a long trip. If possible, introduce the mat or grass at home first. Then bring it to the boat and use the same setup. Dogs like familiar smells and familiar routines.

Useful training tips:

• Use the same toilet command each time.

• Take your dog to the toilet area after sleeping, eating, or drinking.

• Reward immediately when they use it.

• Keep the toilet spot in the same place.

• Do not change the surface too often.

• Be patient with older dogs.

• Practise when you are not in a hurry.

Some owners place a little of the dog’s urine on the mat at first, so the dog understands the purpose. It may not sound elegant, but boat life is rarely elegant behind the scenes.

If your dog refuses at first, do not panic. Many dogs need time. Some may hold on until they go ashore. Others may only use the boat toilet after they realise there is no other option.

This is why the first training session should not happen during a 14-hour passage with rain, waves, and two tired humans whispering, “Please, please, just use the mat.”

Start earlier. Everyone will be happier.

Cleaning and Smell Control

Cleaning matters a lot.

A dog toilet on a boat can smell quickly, especially in warm weather. Salt, sun, urine, and small spaces are not a romantic combination.

For artificial grass or mats, rinse often with fresh water if possible. Use a tray that can be emptied and cleaned easily. Choose cleaning products that are safe for pets, safe for your boat materials, and not harmful to the sea.

Avoid letting urine run freely across the deck or into places where it can collect under fittings, ropes, cushions, or cockpit drains. Boat smells have a talent for becoming permanent residents.

Useful cleaning items to keep on board:

• waste bags

• washable gloves

• fresh water spray bottle

• pet-safe cleaner

• dedicated brush

• absorbent cloths

• spare mat or grass patch

• small sealed bin or waste container

Always dispose of dog waste responsibly. Never throw plastic bags into the sea. In marinas and anchorages, follow local waste rules.

It is not glamorous, but good cleaning habits make sailing with a dog much easier.

And your guests will thank you, even if they never know what almost happened.

What If Your Dog Refuses?

Some dogs refuse to go on the boat.

This is common, especially with older dogs who have spent their whole life going only on land. It does not mean they are bad boat dogs. It just means the routine is unfamiliar.

If your dog refuses, try:

• starting training on land with the same mat

• using a grass-like surface

• keeping the toilet spot quiet and calm

• rewarding small progress

• trying after meals or naps

• giving them privacy

• avoiding pressure or frustration

• asking other sailing dog owners what worked for them

Some dogs need many attempts. Some eventually accept it. Some always prefer shore visits and only use the boat toilet in emergencies.

If your dog regularly holds urine for too long, seems uncomfortable, or has health issues, ask a vet for advice before planning long passages.

A good sailing dog routine should work for the dog, not only for the itinerary.

The boat may have a passage plan. Your dog has a bladder. Both deserve respect.

Marinas, Anchorages, and Local Rules

Toilet routines also depend on where you are.

In marinas, always clean up after your dog and follow local rules. Some marinas have specific dog areas, while others expect owners to walk dogs outside the marina. In busy summer marinas, being a responsible dog owner matters because one careless owner can make life harder for everyone else.

At anchor, check whether dogs are allowed ashore. Some beaches, protected areas, islands, or nature reserves may have restrictions. In some places, dogs are welcome. In others, they are not allowed during certain seasons or in specific zones.

If you are cruising between countries, remember that pet paperwork also matters.

Vaccinations, passports, microchips, and entry requirements can vary, especially for boats crossing borders. You can read more in our guide to what papers you need to sail through Europe with a dog or cat.

A good dog toilet plan is not only about the boat. It is also about respecting local places, other people, and the environment.

Small Dogs, Big Dogs, and Different Personalities

There is no one perfect method for every dog.

Small dogs may adapt more easily to pee pads or a small grass tray. Big dogs may need a larger, stronger setup. Puppies may learn faster because they are still forming habits. Older dogs may need more time and patience.

Personality matters too.

Some dogs are relaxed and will use the new toilet area after a few tries. Some are sensitive and need privacy. Some are stubborn. Some look at the artificial grass, then look at you, then look back at the shore like they are contacting their lawyer.

That is normal.

The best solution is the one your dog accepts and you can keep clean and safe.

A Practical Boat Dog Routine

For everyday cruising, a simple routine helps.

Before leaving the marina, take your dog for a good walk. At anchor, decide whether shore trips are safe and allowed. Keep the onboard toilet ready as a backup. On longer passages, encourage your dog to use the toilet area before conditions become rough.

A basic routine could look like this:

• walk before departure

• offer water regularly

• keep the toilet area accessible

• use the same command

• reward successful use

• clean immediately

• watch for discomfort

• plan shore visits when possible

Like most things on boats, the secret is preparation. If you wait until the urgent moment, everything becomes more dramatic.

And dogs are already dramatic enough when a fender moves unexpectedly.

The Honest Answer

So, how do dogs go to the toilet on a boat?

Some go ashore by dinghy.

Some use pee pads.

Some use artificial grass.

Some learn a deck toilet spot.

Some take time, training, and a lot of patient encouragement.

There is no perfect answer for every dog. But there is usually a workable routine.

The most important thing is to plan before you need it, train gently, keep the area safe, clean properly, and remember that your dog is adapting to a very unusual life.

For us, boat life can feel adventurous.

For a dog, it may simply feel like home has started moving.

So give them time. Give them a clear place to go. And maybe give them a treat when they finally understand the strange little bathroom you built on deck.

They have earned it.
