Before Vytherm, checking my anxious rescue's temperature meant a fight every time. Now I just point, click, and she barely notices — it's become part of our calm bedtime routine.

The Thermometer Dogs Don't Fight
Color-Coded Health Alerts
A green, yellow, or red glow tells you instantly if your pet's temperature is normal, rising, or high. No charts, no guesswork.
Crystal-Clear Night Display
A bright three-color backlight keeps the display sharp in total darkness, so late-night fever checks are calm, clear, and stress-free every time.

Secure, Comfortable Grip
An ergonomic, non-slip handle keeps Vytherm steady in your hand, even when your pet won't sit still. Confident readings, every time.
Auto Shutoff Saves Battery Life
Running on two AAA batteries, Vytherm powers down after 15 seconds of inactivity to save energy. Less waste, more readings between changes.

Based On Real and Honest Experiences
My old dog has recurring health issues, so I check her temperature most mornings. Vytherm gives consistent readings every time, and the 32-reading memory means I can finally show our vet real patterns, not guesses.
I'd read that non-contact thermometers don't always work consistently, so I almost gave up before trying. But Vytherm gave the same reading three times in a row on my nervous foster dog, and now it's the first thing I grab.
