When you think your dog might have a fever, the one fact your vet wants is an actual temperature reading - not a guess from warm ears. PetHealthLog gives you one place to log each rectal temperature with its time, keep the normal range and the urgent cut-off in view, and watch the trend across the day. Free, no account, works offline.
A dog's normal body temperature sits higher than a person's - generally around 100 to 102.5°F (about 37.8 to 39.2°C). A reading above roughly 103°F (39.4°C) is usually considered a fever, and vets often describe a temperature above 104°F as a reason to be seen right away. Those numbers are why warm ears or a dry nose tell you almost nothing - the only way to know is to measure.
Taking it accurately means a digital thermometer used rectally, lubricated and inserted about an inch, which reads in around a minute. It helps to have your vet or a vet nurse show you the first time. Once you have a number, the next problem is keeping track of it - a single reading is far less useful to your vet than several readings with their times, so a trend is visible.
A simple log fixes that. PetHealthLog is free, needs no account and works offline, so you can record each temperature with the time you took it, keep the normal range and the urgent cut-off listed in front of you, and watch whether things are climbing, holding or settling - one clear timeline you can read to your vet over the phone or hand them at the clinic.
What the tracker actually does
Log each reading with its time
Record every temperature with the time you took it, so a trend builds across the hours rather than relying on one number or your memory in a stressful moment.
Keep the normal range in view
Have the general normal range - around 100 to 102.5°F - listed in front of you, so each reading lands in context instead of as a bare number.
Keep the urgent cut-off in view
Have the temperatures often described as urgent - above about 104°F, or a reading that keeps climbing - in view, so you know which reading means calling the vet now.
Track more than one dog
If more than one dog is being watched, log each separately so every pet has its own clean temperature record for the vet.
A vet-ready PDF
Export a clean timeline of every reading and its time - so a phone call or a clinic visit starts from real numbers instead of trying to recall them.
What a temperature check often looks like
Watching a dog's temperature tends to follow these checkpoints - this is a general guide, not a schedule for your dog. Use the free tracker to record each step and share the history at your next visit.

What is a normal temperature for a dog?
As a general guide, a dog's normal body temperature is usually around 100 to 102.5°F (about 37.8 to 39.2°C), a little higher than a person's. A reading above roughly 103°F is commonly considered a fever. These are general figures - your veterinarian advises what is normal and concerning for your dog; the tracker just keeps the record.
When is a dog's fever an emergency?
Vets often describe a temperature above about 104°F, or one that keeps climbing, as a reason to be seen right away - especially alongside lethargy, vomiting, shivering or not eating. The tracker keeps the cut-off in view, but whether a reading is an emergency for your dog is your vet's call; when in doubt, contact an emergency clinic now.
How do I take my dog's temperature?
Accurately, it is a digital thermometer used rectally - lubricated and inserted about an inch - which reads in around a minute. You cannot tell a fever by feeling the ears or nose. It helps to have your vet or a vet nurse show you the first time. The tracker is for recording the number once you have it, not for measuring.
Is this a substitute for veterinary advice?
No. PetHealthLog is a record-keeping tool, not veterinary advice. It does not diagnose a fever, find its cause, or treat anything. A high or rising temperature is handled by a licensed veterinarian - contact your vet, and if your dog's temperature is above about 104°F or it is collapsing, shivering or struggling, go to an emergency clinic now. The tracker just records the readings you took and when.
Keep your dog's temperature readings on one timeline
Informational only - not veterinary advice. PetHealthLog helps you keep records and stay organised, but it does not diagnose, prescribe, or decide your pet's treatment. Diagnosis and any plan should be decided with a licensed veterinarian.
Note when and how heavily your dog pants to share with your vet.

When to contact a vet immediately
A tracker is for patterns over time — it is not for emergencies. Contact a veterinarian or an emergency clinic right away if your pet has difficulty breathing, collapses or cannot stand, has a seizure that does not stop or seizures that repeat, is straining to urinate without producing urine, has severe bleeding, or may have swallowed something toxic (see ASPCA Animal Poison Control).
