Your hair is not the only one that hates humidity–so does your dog! Heat and humidity are not your companions friend any more than they are yours. It sounds to me like the friends your Monty deMutt was trying to play with may have been heading toward heatstroke.
Heatstroke, or hyperthermia, occurs when the body cannot combat the excessive heat it’s encountering. Some of the most common symptoms are lethargy, panting, dehydration, excessive drooling, and little to no urine output.
If you and Monty deMutt want to play outside during the hot times of the day, the best way to prepare is to make sure you have plenty of water on hand for you both–and maybe a spray bottle to mist his fur with. You could also just let him have some fun chasing fish at the local lake.
If you see an animal in distress, help their human by giving them water (not too cold at this point or it will cause the blood vessels to constrict and the animal to get hotter) and finding shade for them. If their human isn’t around or they don’t appear to have one, give them water–again, not too cold–and wrap them in a cool towel. Call your local police or animal control to come and assist.
Have a fun and cool summer!
