Short muzzled breeds – Bulldogs, Boxers, Pekinese, Pugs, Persian Cats, and other pets with flatter faces are not able to effectively cool themselves by panting and should not be outside for long periods of time.
Special needs pets – Puppies under 6 months, elderly and overweight pets and those with heart or lung diseases have a hard time regulating their body temperature and should be kept in air-conditioned rooms as much as possible.
Active animals – Limit intense exercise in the summer months. Exercise your pet in the early morning or late evening. Be alert for the possibility of overheating and over exertion, even in moderate temperatures. Many dogs will continue playing or running to keep up with their owner, to the point of exhaustion.
Grooming – A matted, or poorly maintained coat will retain heat.
Indoors and out – Pets need access to fresh, cool water
If you love them, leave them at home – Despite warnings not to leave animal in cares, every year there are reports of dogs dying after being left alone in vehicles, some for very short periods of time.
Although it may not seem very warm outside, the interior of a car can heat up to dangerous levels very quickly even with the windows cracked open.
Parking in the shade is not a safe alternative. The car can literally act as an oven, heating up hotter and hotter the longer it sits.
Before you put your pet in the car, ask yourself if you really need to take your pet with you. If your pet will be left unattended in the vehicle for any period of time, it is best to leave him safely at home.
