Dog-friendly beaches and resorts that cater to canines have grown in popularity in the past few years and can be found around the country. Here's few tips to help ensure a fun outing.

If you planning to visit a public beach, check with state or local governments to make sure dogs are welcome. For example, dogs are prohibited on public beaches in Seattle. Look for signs posted at area parks such a Green Lake. Fido's little dip in the water can cost you a hefty fine.

If you're headed to a dog-friendly hotel or resort, find out in advance what the rules are so you and the pooch don't get kicked out or hit with extra costs.

For beaches that allow dogs, remember to bring a leash, poop pick-up bags, fresh drinking water and a bowl.

Be aware that the biggest risk for a dog at the beach is salt poisoning from the water, said Dr. Tina Wismer, medical director for the Animal Poison Control Center run by the American Society for the Prevention of Cruelty to Animals in Urbana, Ill.

"Dogs who like to retrieve balls and other objects out of the water can ingest enough water to make them sick," she said. In fresh water, the games are the same but the problem can be drinking too much water, or water intoxication.

"The most common treatment of salt poisoning or water intoxication is intravenous fluid therapy," the veterinarian said.

Other things dog-owners should watch for:

"Dogs can get sick from eating dead fish, crabs, or even bird feces," Wismer said. "If a dog ingests dead animals, or feces found on the beach, they may need fluids and antibiotics, depending on what and how much was ingested."

In some areas, jellyfish can show up in the water. Their stings can be very painful for both dogs and humans. "If a dog is stung by a jellyfish, pain medication could be necessary," Wismer said. Some sea stars are also poisonous and can cause severe vomiting and drooling in a dog.

Don't assume your dog can swim or even likes the idea of swimming. Some dogs are happy to just wade at the water's edge.

Make sure there is shade near by so you and the pooch can take break out of the sun.

Check the paws, prolonged exposure to hot asphalt or sand can cause burns.

Also avoid overexertion in hot weather. Try walking or playing early in the morning or late in the evening when it's usually cooler.
