Dogs naturally have a higher body temperature than humans, ranging between 101 and 102.5 degrees Fahrenheit. When a dog's body temperature exceeds 103 degrees, he has a fever and may have symptoms such as lethargy, vomiting, diarrhea and loss of appetite. A fever of more than 106 degrees is considered excessive and can be fatal.

Effects of High Fever

Just like in humans, a high fever will cause intensity of symptoms such as vomiting and fatigue, as well as potentially dangerous convulsions and confusion. The loss of liquids through diarrhea and vomiting combined with the fever can cause dehydration, especially if your dog has no interest in water or cannot keep water down. You can sponge your dog with cool water to help lower the fever, and you should contact your vet immediately if your dog's fever rises above 105 degrees.
