How to use the pet hypothermia temperature check
Enter the rectal temperature you measured, the outdoor temperature right now, the body size band by weight, and tick the exposure conditions that apply. The tool shows where your reading sits against the published hypothermia floor and how many exposure factors apply, which helps before a winter walk or after a long spell outdoors.
The comparison uses the veterinary clinical floor that treats a rectal temperature below 98 to 99 ℉ (36.7 to 37.2 ℃) as hypothermia, and the normal range of 100.5 to 102.5 ℉ (38.0 to 39.2 ℃) that veterinary practices and clinical references share for dogs and cats. Both ranges assume a rectal reading. Figures compiled as of October 2026.
This tool does not grade hypothermia as mild, moderate or severe, because the cut-offs between those stages differ between sources and no single agreed table exists. The factor count is a tally of exposure conditions, not a diagnosis, and the tool does not identify frostbitten tissue. This tool is for reference only and does not replace veterinary care. Contact your veterinarian right away if shivering stops or your pet becomes unresponsive.
Frequently asked questions
The reference band assumes a rectal reading, so other sites are hard to compare directly. Use a rectal temperature when you can, and treat other methods as a rough check only.
The cut-offs between stages differ from source to source, so there is no single agreed table. This tool compares one published floor instead of inventing a staging chart.
It only means there is no hypothermia right now, not that the exposure itself is fine. A wet coat and wind pull body heat away fast, so move indoors and measure again shortly.
