Thermometer that doesn't beep

Odd request, but if anyone has a thermometer that doesn't make noise when its reading temperature, please let me know what kind it is. I dont care if its a traditional thermometer or the ear/forehead reader type.

Beeping noises give my dog anxiety. Any thermometer we have had beeps and causes her to tremble and shake for hours. ( not looking for any "well put her outside when you do it " type of advice 🙄)
