A dog's normal body temperature ranges from 101 to 102.5 degrees Fahrenheit, which is significantly higher to humans whose body temperature ranges from 97.6 to 99.6 F. A temperature of more than 103 F is considered a dog fever. When temperatures reach 106 F, serious and fatal complications can occur.

How do you tell if a dog has a fever without a thermometer?

You're probably familiar with the tried and true method many dog owners have relied on to see if their dog has a fever: Feel his nose. If it's wet and cold, he's fine. If it's hot and dry, he probably has a fever.

How can you tell if a dog has a fever at home?

To take your dog's temperature, first coat the thermometer with a lubricant such as petroleum gel or baby oil. Next, gently insert the thermometer about one inch into your dog's anus and wait for results. Most thermometers sold for this purpose will take less than 60 seconds to register.
