Question: No problem right now. I just wanted to know how to tell if my dog is running a temperature. When my own kids are sick, I feel their foreheads to see if they have a fever. How do I tell with a dog?
The only way to know for sure whether a dog is running a fever, is by taking a rectal temperature. You can certainly do this at home with a human rectal thermometer inserted about 1-2 inches after coating the tip with vaseline. Leave it in for 1-2 minutes (though a high fever will register in less time). Because dogs have more variable temperatures with normal ranging from ~100-101.5, it is hard to tell just by feel. With that said however, when you suspect a fever, if you can’t take a rectal temperature, try feeling a hairless area such as the inside of the ear, or groin.
