Take care of pets

Montgomery County Animal Care and Control is reminding everyone to take precautions for their animals. Last year, Montgomery County had 10 heat stroke calls and at least five deaths for dogs who were either left outdoors or in a vehicle without access to shade or water.

Owners are urged to ensure dogs are kept inside, or at least have access to both shade and fresh water all day. Never leave a dog in an unattended car.

Heat safety tips

“Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances,” the NWS said.

The NWS advises taking extra precautions if you work or spend time outside. When possible reschedule strenuous activities to early morning or evening.
