Vets say right now can even be more dangerous for pets than in the peak of summer, because the weather fluctuates rapidly.
"It quickly will get up to 150, 160 degrees on some of these 90, 100 degree days and you will cook your animal," said Dr. Chris Dobbins at Pet ER.
Dr. Chris Dobbins, said leaving pets in cars during the heat can turn deadly fast.
In fifteen minutes the temperature in an SUV soared to 130 degrees.
Beth Caffrey with the Central California SPCA says the calls have already started.
"That's the number one call that we get and then past that is going to be animals that are stressed because they can't get out of the heat," said Caffrey.
If outdoors, the best thing is to make sure your pet has plenty of water.
"Sometimes the little small bowls, they can step on them and fall over and then they're empty and they don't have any water," said Dr. Dobbins.
A kiddie pool is a good idea to keep your pet cool and you can even buy a mister for under $10 shade is also a precious commodity.
"Sometimes people will notice a certain time of day and they're like there's a lot of shade out here...but that doesn't mean it stays the same all day long," said Caffrey.
If there are any signs of heat stress, take your pet to the vet to help get properly cooled off.
Excessive panting can be a danger sign.
Also, be mindful of extremely hot cement and asphalt when taking your pet for a walk.
"You've got tennis shoes on probably, they don't. So be careful of that, they will blister," said Dr. Dobbins.
Keeping pets indoors when the weather heats up is always a good idea.
