Large Animal Rectal Thermometer - Patterson Veterinary
I do not recommend an ear thermometer; they are not accurate, and if you don’t know how to use it correctly, you can do damage to your animal’s ear.
Digital thermometers have an easy-to-read numerical display in either Fahrenheit or Celsius. They calibrate themselves after being turned on…no shaking required. Digital thermometers are inserted into the ear canal and need to be close to the ear drum to get an accurate reading. Due to the many sizes and shapes of the canine and feline ear canal, digital temperatures aren’t always precise. Plus, the presence of hair, wax, and debris in the ear canal can affect accuracy.
The second experiment was conducted 5 d after the conclusion of the first and followed the same process, except the rectal temperature measurement was obtained by using the common digital thermometer. The digital rectal thermometer was sanitized by wiping with 70% ethyl alcohol solution between ferrets. The microchip temperature was obtained immediately after obtaining the rectal temperature, as done in the first experiment 1.

4. Remove the thermometer and read the temperature. A dog’s normal rectal temperature is 101.5 Fahrenheit or 38.6 Celsius.. If it ranges between 100.5 and 102.5 degrees Fahrenheit or 38 and 39 Celsius, then your animal is not in serious trouble. Anything higher or lower than that, you need to contact me right away and let me know what else is transpiring with your animal.The measurement of an animal's body temperature is important for evaluating its health. Even though rectal thermometry, considered the clinical ‘gold standard,’ is thought to be minimally invasive, its use in research macaques is suboptimal given the requirement for sedation or extensive physical restraint. The use of anesthetics that can alter body temperature measurements, and the potential stress associated with manual restraint and intrusive thermometer placement for a rectal measurement both point to the need for an alternative to rectal thermometry in these nonhuman primates.Obtaining an animal's body temperature is essential for the assessment of its clinical status. For many species, rectal thermometry is the technique used most often; however, this method in macaques typically requires sedation or considerable physical restraint. A noninvasive and inexpensive temporal artery (TA) thermometer was evaluated as an alternative method for collecting body temperature measurements from macaques used in neuroscience research. Rectal and arterial temperatures were obtained from 86 macaques (mean age, 10.2 y) that had received ketamine (10 mg/kg IM) or Telazol (5 mg/kg IM); the arterial measurements were taken from behind the right ear. In addition, arterial temperatures were measured behind both ears in a cohort of awake, chaired macaques with cephalic restraint pedestals only (n = 8) or with cephalic restraint pedestals and recording chambers (n = 14). Within-subject repeatability for TA thermometry and agreement between rectal and arterial temperature measurements were assessed by using the Bland–Altman method. Temperature measurements indicated that values from TA thermometry were lower than those from rectal thermometry by 1.57 °C with a 95% agreement limit of ± 1.27 °C. Results show satisfactory repeatability with TA thermometry and agreement between arterial and rectal temperatures, demonstrating that TA thermometry can be a valuable tool in conscious, chaired macaques with restrained heads.Previous studies using laboratory animals have evaluated various other thermometry methods, including noncontact infrared thermometry,,,,, telemetry,, subcutaneous implantable microchip thermometry,,,,,,,,, and tympanic thermometry,,,, against the standard of rectal thermometry. Infrared thermometry was shown to be invalid in rhesus and cynomolgus macaques, presumably because of the relatively large surface area measured and the influences of ambient temperatures, wet fur, and the presence of hair., Telemetry and microchip thermometry both require expensive equipment and device implantation but then allow for measurements to be taken without further handling of animals. While temperatures from microchips in rhesus macaques agreed more closely with rectal temperatures than did those measured by infrared thermometry, microchip readings were inconsistent, and the macaques became stressed after repeated attempts to position them for readings in the cage. Although tympanic thermometry can be performed in conscious, chair-trained nonhuman primates, this method may cause discomfort, even after a period of acclimation. In addition, the accuracy of tympanic thermometry depends on precise placement of the probe.,,,
