Dogs that spend most of their summer days inside are protected from many warm weather hazards, but only if the temperature inside the home remains within a healthy range. In an effort to reduce energy usage and costs, some pet owners shut off fans and air conditioning when they leave the house in the morning and turn them on when they return later in the day. However, when temperatures outside reach dangerous levels, temperatures inside the house can, too. Being shut inside a hot house can be deadly for your dog. Dogs can’t sweat; they rely heavily on panting to cool themselves off. When the temperature in the environment increases, panting becomes less effective. This means that your dog could be locked inside with minimal options for cooling down.
