There’s nothing like spending a beautiful summer day near the water. And it’s even more fun when you get to bring your pets along. But whether you’re packing your bag for the beach or spending the day on a boat, our experts at ASPCA Poison Control want to remind you to keep a few things in mind to ensure your summer adventure stays safe.

Water: Ocean water is high in salt content and inadvertent ingestion can cause vomiting, diarrhea and increased thirst. In severe cases, ingesting saltwater can disrupt a pet’s electrolyte balance, which may affect the heart and nervous system and require hospitalized treatment. The best way to prevent this is by offering plenty of clean, fresh water to your pet. This not only prevents them from drinking the ocean water but helps prevent heatstroke and dehydration.

Signs of heatstroke include excessive panting, drooling, and lethargy.

Sunscreen: Sunscreen is an important outdoor staple for humans and sometimes pets too — especially those with short coats and light-colored exposed skin. Pet ingestion of human sunscreens can cause vomiting, diarrhea and sometimes allergic reactions. Sunscreens may also contain xylitol, an artificial sweetener that can cause low blood sugar and liver damage in dogs. If you need to protect your pet from the sun, stick with products that are specifically formulated for animals, and ask your veterinarian for recommendations.

Sand: Pets may find it fun to play and dig in sand, but eating sand should be discouraged. Sand can cause vomiting and diarrhea and large ingestions can sometimes cause a blockage, requiring hospitalization and intensive treatment.

Jellyfish: There are many different species of jellyfish in the ocean, some being more concerning than others. Ingestion of certain types can cause gastrointestinal upset, muscular, cardiac and neurological effects. If pets are stung by jellyfish, they can also experience pain, redness and irritation on the skin, much like human exposures. If either occurs, please contact your veterinarian or ASPCA Poison Control at (888) 426-4435.

Dead Fish: Dead fish may be appealing toys or snacks for pets, but ingestion can cause vomiting and diarrhea. The skeleton, scales and sharp spines may also cause physical injury to the mouth and digestive tract. Some fish species carry additional toxin concerns when eaten, which can lead to complications such as difficulty breathing, heart and nervous system effects. When in doubt, it’s always best to steer your pet away from anything washed up on shore.

Bonus Boat Safety Tips:

Life Vests: While many dogs are natural swimmers, the ocean can be unpredictable and boating accidents can happen. Even dogs that are confident swimmers can become disoriented or tired in an emergency, so a life vest is always wise.

When choosing a life vest, opt for one that fits snugly, with adjustable straps and a sturdy handle for easy lifting. Bright colors and reflective strips are also essential for increased visibility. Let your pet get used to wearing the vest on land before taking them in the water or on the boat.

Boating Chemicals: Boats often involve substances such as fuel, antifreeze and cleaning agents that can pose danger to pets. Exposure to these items, whether through ingestion, skin contact or inhalation, can lead to a variety of ailments. Always store chemicals securely in sealed, pet-proof containers, and avoid leaving chemicals unattended or within reach of your pet. Be especially careful when fueling or cleaning the boat.

During any visit near the water with your furry friends, we suggest stocking up on fresh water, pet dishes, your pet’s favorite treats and meals, and something to keep your pet cool, like an umbrella for shade. Never leave your pet unattended and watch out for the above items so that everyone can enjoy a fun, safe summer day!

If you suspect that your pet ingested something potentially toxic, please call your veterinarian or ASPCA Poison Control at (888) 426-4435 immediately.
