RHINELANDER - Temperatures outside might feel nice.
But inside your vehicle, the heat can get downright dangerous.
When temperatures are in the 70s, it can get as hot as 118 degrees inside a car.
This can be potentially deadly to pets left in parked vehicles.
"They'll get an elevated temperature, which can then lead to brain swelling, which will lead to seizures. If you don't need to bring them along, it's just best to leave them home," said Veterinarian Alison French.
Just because you see a dog in a car on a warm day doesn't always mean it's in danger.
Patrol Officer Ben Curtes of the Rhinelander Police Department says to look for signs of distress.
"Just take a second. Observe the dog. Observe the conditions. See if that dog is getting air. Maybe the car has closed windows but the air conditioner is running," said Curtes.
Curtes also says it's not illegal to leave a dog in a parked car, but to call the police if you believe a dog is in severe distress.
