SUMMER HEAT CAN BE DEADLYHeat stroke is due to an increase in body temperature generally related to high environmental temperature or inadequate ventilation. The process involves the dilation of blood vessels in response to high body temperature. As blood begins to pool, the blood pressure in the body drops rapidly. With blood circulation down, the bodies’ own cooling mechanisms stop and core body temperature can reach over 109 F (normal = 101.5 F). As the body temperature continues to rise, sensitive cells (including those in the brain and lining the intestinal tract) die. The progression of clinical signs starts with weakness and blank/dazed expression, vomiting, diarrhea, muscle cramping and shaking, eventual collapse and death. If you think your pet is experiencing heat stroke, the best first aid is to submerge him in cool water then seek treatment. Prevent this by providing plenty of fresh, cool water daily and a well-ventilated shelter. Animals should NEVER be locked in a car even with the window cracked, or tied up in a yard or pen without shade. If you suspect you pet may have become overheated, please call your veterinarian immediately. |
