Never leave your dog unattended in direct sunlight or in a close vehicle heatstroke can occur and lead to brain damage or death. Signs of each store or panting, drooling, rapid pulse and fever. Immediately immerse the dog in cold water, and seek emergency veterinary assistance.

Never leave your dog unattended in a pot, parked car. When it's only 80° outside, the inside of a car can heat up to more than 120° in just minutes. Leaving the windows partially rolled down will not help. Your dog is susceptible to heat stroke and possible death in these conditions. Always make sure your dog has access to fresh water.
 
Taking your dog to the beach can be a great way to spend a beautiful summer day. Provide plenty of fresh water and shade for your dog dogs can get sunburned, especially short haired dogs and ones with pink skin and white hair. Limit your dog's exposure when the sun is unusually strong, and apply sunblock to his ears and nose 30 minutes before going outside.

Not all beaches permit dogs. Check local ordinances before you begin your excursion.  The majority of dogs can swim, and they love it. But dogs entering the water for the first time should be tested. Never throw your dog in the water. Start in shallow water, and call your dog's name. You can also try to coax him in with a treat or toy. But always keep your dog within reach.  Another way to introduce your dog to the water is with a dog that already swims and is friendly with your dog. Let your dog follow his friend.
 
If your dog begins to doggie paddle with his front legs only, lift his hind legs and help him float. He should quickly catch on and within keep his back and up.  Swimming is a great form of exercise, but don't let your dog overdo it. He will be using new muscles and may tire quickly.  The careful of strong tides that are hazardous for even the best swimmers. Never leave your dog unattended. You should always be in a position to help you get out of the water.
