When we humans are active outdoors when the weather is hot we usually find ways to cool ourselves off, such as drinking lots of water, and or going indoors to chill out. But when dogs are engrossed in what they do, they forget that they are actually tired and thirsty and they may spend a long time outside without replenishing their body with water, or cool off.
Heat problems dogs experience usually come from heat stress, which results from too much exposure to high temperatures, or from heatstroke, which is also from too much sun but with high humidity levels. If the dog has lost a lot of fluids and does not rehydrate it may cause it to experience cellular breakdown, heart failure and even brain damage.
There are some dogs which are more prone to internal injuries because of heat stress and heatstroke. If your dog has cardiovascular conditions, or respiratory issues, overweight, or is short-nosed buried, it may experience damage three times faster than other dogs.
Pay attention and care to your dog if it tends to stay out long in the hot weather, and look out for signs that show that it may be suffering from heat conditions.
