Heatstroke
Summertime in Texas means average daily temperatures exceeding the upper 90's, and humidity that is almost unbearable. Extreme temperatures mean increased risk of overheating, or heatstroke -- a potentially fatal situation. The most common mistake pet owners make is leaving their pet in the car. Even if only for a few minutes, this is a deadly decision. However, there are several other ways dogs are affected by the heat. Many dogs escape the confinement of their yard, run at large, or go on long hikes without adequate water or shade protection. Pets are susceptible even on days that don't seem particularly hot.

Use caution when leaving your pet in an enclosed area (like a vehicle, shed or open pen that is exposed to direct sunlight), even in the shade, on hot and humid days. When going to such summer activities as outdoor flea markets, fairs, carnivals, concerts, parties and barbeques, have ready access to water and watch for signs that heat is building up within your pet. Panting is a dog's single best method of dissipating body heat, and panting generates more body heat. When the body temperature becomes too high, pets will appear very distressed and weak -- this is an emergency situation, and you should seek medical attention immediately.

Unfortunately, in spite of vigorous emergency procedures, not all heatstroke victims survive. It is not recommended for pet owners to try to lower the animals body temperature on your own. Often times people will use a cold-water rinse, which can send the animal further into shock, or cause death. Many tissues in the body are made of proteins that can be damaged by even small amounts of extreme heat, including brain tissue. The veterinarian's efforts are aimed at preventing further damage and helping damaged systems recover. Don't hesitate if you think your pet is overheated -- when the dog's body temperature starts to rise, heatstroke is only minutes away.
