When you are a pet owner, extremely hot weather requires a few adjustments. For example, in the summer, Bentley (the world's most loveable Cavalier King Charles Spaniel) and I schedule our daily walks before 7am or after sundown to avoid the hottest part of the day. In cooler seasons, I generally don't bring water with us. But in the summer, I carry a bottle of water on our walks in case Bentley needs to stop for a break from the heat.

It's important to remember that dogs can suffer from heat stroke more quickly than you might imagine. So, take some basic precautions this summer to protect your Cavalier King Charles Spaniel.

• Restrict outdoor exercise to the early morning and late evenings when temperatures are cooler.

• Carry water with you. Watch your Cavalier Spaniel for signs that he is slowing down, panting heavily and becoming overheated. Stop and take a water break in the shade. Then, head for home as soon as your dog is rested.

• Needless to say, dogs kept out of doors need plenty of shade and fresh water. Get out that kiddie pool and let your pet take a swim to cool off. And in unusually high heat, check the outside temperature in your dog's shaded area - it might still be 80 degrees in the shade and that's too hot to leave him outdoors. Even if you're not home during the day, most of us can find an air-conditioned "doggie daycare" facility near our homes.

• Never, never, never leave your Cavalier King Charles Spaniel unattended in a parked car. Even with the windows slightly opened and parked in the shade, the internal temperature of your car can heat up very quickly and be fatal to your dog before you know it. Your pet can die in less than 10 minutes, so don't take a chance by leaving him in a car alone.

• If you are planning a long car trip with your Cavalier Spaniel, consider buying window shades for the back seat windows to help keep sunlight off your dog. Sometimes drinking too much water can upset a dog's stomach when you're traveling. An alternative is to bring along some ice cubes to help cool your pet more slowly.

How do you recognize heat stroke in your pet? Obvious signs are heavy panting, weakness and stumbling. A heat stroke victim will eventually collapse and fall unconscious. Heat stroke can raise your Cavalier Spaniel's body temperature to the point where a chemical reaction results that actually breaks down cells in your dog's body.

If you keep a rectal thermometer in your emergency first aid kit (and you should!), take your Cavalier King Charles Spaniel's temperature. If's it's approaching 105 degrees, call your veterinarian. In the meantime, put your pet in a cool bath, or at least sponge him off, paying special attention to wetting down his belly and inside of his legs. When your dog's temperature drops to 103 or 104 degrees, you should remove him from the bath to avoid bringing his temperature down too quickly. Hopefully, by this time, you've reached your vet. If not, head for the closest emergency clinic.

Summer is a wonderful time to enjoy our four legged friends, and a few common sense measures will go along way toward proper pet care and prevention of heat stroke.
