Pet experts warn of summer heat and toxic algae risks for dogs

Pet care experts are issuing warnings regarding summer environmental hazards for dogs, specifically extreme heat and toxic cyanobacteria.

Regarding rising temperatures, specialists note that dogs can transition from normal activity to life-threatening heat exhaustion within minutes. Factors such as age and breed increase vulnerability; older dogs and flat-faced breeds like Pugs, Shih Tzus, and Boston Terriers are at higher risk due to breathing difficulties. Warning signs include heavy panting, pale gums, and unsteady movement. Experts recommend limiting outdoor exposure, providing shade, and ensuring constant access to fresh water.

Additionally, Angell Animal Medical Center has warned of the dangers posed by cyanobacteria, or blue-green algae, which thrives in warm, stagnant water. This microscopic bacteria can be found in fresh, brackish, and salt waters. Because toxic cyanobacteria may not always change the water's appearance, experts advise against letting pets drink from or swim in still bodies of water, especially those with a foul odor or a ‘spilled paint look’.
