MADISON, Wis. -- Heat stroke in animals is a big threat during the warm summer months, but in many cases, experts said the potentially deadly threat can be avoided.

Animal experts are reminding pet owners to keep outside time for pets to a minimum during warm days, look for shade and keep pets hydrated.

Experts said owners should keep a close eye on things that could be signs of a bigger problem.

"We can tell when we get really hot and thirsty, but dogs can't really show that until the very last moment when they're very hot and tired, so take them to the vet right away," said Gayle Viney, of the Dane County Humane Society.

Pet owners who WISC-TV spoke with said they are already doing things like closely watching pets and being mindful of hot temperatures outside.

"We try to get out here before 10 so the sun isn't too hot on these guys. This (dog) doesn't care; she's just out here to have sniffs. It's our high energy time and we get them tired so they sleep during the heat of the day, siesta from about noon to 4 (p.m.)," said Becky Oliva, a dog owner.

Experts said one of the most important reminders is to never leave an animal inside a car when it is hot outside.

Those worried about heat stroke in their pets should look out for signs like rapid panting, a bright red tongue, red or pale gums, thick and sticky saliva, weakness and dizziness. Experts said that using a hose to spray down your animal can actually make things worse because their bodies don't know how to respond to the extra moisture. The best thing pet owners can do is to keep pets hydrated and move them indoors if at all possible.
