Drop in Rectal Temperature in Dogs
When to visit the vet?
Non-urgent see a veterinarian within 2–3 days
RED for a non-pregnant dog, or a dog that seems unwell with hypothermia and signs of shock (pale mucous membranes, prolonged CRT, weak pulses, reduced responsiveness). For a pregnant bitch: RED if there are no contractions >24 hours after the temperature drop (see No. 1).

Definition of
Drop in rectal temperature in dogs, also known as hypothermia, refers to a condition in which a dog’s body temperature falls below the normal range, which is typically below 37.5 degrees Celsius.
Can Occur with the Following Diseases:
Grundlagen und mögliche Ursachen
A dog’s normal body temperature is between 38 and 39.2 degrees Celsius. Various factors can influence body temperature, including age, breed, activity level, and ambient temperature. Hypothermia occurs when the body’s heat production is insufficient to offset heat loss, resulting in a drop in body temperature.
Possible causes of hypothermia include prolonged exposure to cold temperatures, shock, certain metabolic disorders such as hypothyroidism, as well as acute illnesses or injuries. Young and old dogs are particularly susceptible because their bodies are less able to regulate heat effectively.
A common cause of hypothermia in dogs is being in cold weather without adequate protection. Dogs that fall into water or are in the rain for extended periods can also be at risk. In addition, some medications or anesthetics can impair a dog’s ability to regulate its body temperature.
Conditions such as renal failure or heart failure can also lead to hypothermia, as they negatively affect overall metabolism and circulation. Infections or Inflammatory conditions that increase the body’s energy use can also disrupt temperature regulation.
Typische Begleitsymptome
- Weakness: Dogs with hypothermia often show general weakness and may not be able to move or stand up normally.
- Slowed breathing: A decreased respiratory rate is a common sign of low body temperature as the body tries to conserve energy.
- Stiff muscles: The muscles may become stiff and inflexible, further restricting mobility.
- Confusion or apathy: affected dogs may seem disoriented or respond less to stimuli than usual.
- Irregular heartbeat: The heart rate may decrease or become irregular, which can be life-threatening as hypothermia progresses.
Wann zum Tierarzt?
A veterinarian should be consulted immediately if a dog’s body temperature falls below 37.5 degrees Celsius and the above symptoms occur. Rapid action is required, especially if the dog no longer responds to stimuli or its condition deteriorates rapidly.
A sudden drop in temperature may indicate a serious underlying condition that requires immediate medical treatment. Even if the dog barely eats, drinks, or moves, it should be examined by a veterinarian as soon as possible.
Symptomerkennung für den Tierhalter und tierärztliches diagnostisches Vorgehen
To detect hypothermia, the pet owner first measures the dog’s rectal temperature. This should be done with a digital thermometer, as it provides more accurate results. If hypothermia is detected, the dog should be taken to a warm environment and wrapped in blankets while the veterinarian is contacted.
The veterinarian will recheck the dog’s temperature to confirm hypothermia and then perform a thorough clinical examination. This includes listening to the heart and lungs, as well as assessing the mucous membranes and capillary refill time. Blood tests may be done to check for infections, organ function, and electrolyte imbalances.
Further diagnostic tests may include X-rays or ultrasound examinations, especially if there is suspicion of an underlying condition causing the hypothermia.
Was kann der Tierhalter tun und professionelle Therapieoptionen
The pet owner can take immediate steps to raise the dog’s body temperature until professional help is available. This includes wrapping the dog in warm blankets and placing warm, not hot, water bottles near the body to ensure even warming.
It is important not to place the dog directly on a heating source, as this can cause burns. Instead, warming should be gradual to avoid overtaxing the circulation. The room in which the dog is located should be kept warm, and drafts should be avoided.
The pet owner should also make sure to provide the dog with access to warm water to avoid dehydration. If there is loss of consciousness or severe weakness, the dog should be placed in Lying on side and calmed while waiting for the veterinarian to arrive.
Ausblick auf aktuelle Forschung
Current research on Drop in rectal temperature in dogs focuses on the underlying physiological mechanisms that can lead to hypothermia. Scientists are investigating how various factors such as ambient temperature, stress, food intake, and physical activity can influence dogs’ body temperature. More recent studies have shown that the hypothothalamus plays a central role in regulating body temperature by acting as the body’s thermostat. Research in neurobiology is examining how neural circuits and neurotransmitter affect the hypothalamus’s thermoregulatory function.
Another research focus is on genetic predispositions that could make certain dog breeds more prone to temperature fluctuations. Researchers are analyzing genetic markers and DNA to find out whether there are specific genetic factors that increase the risk of hypothermia. In the long term, this research could help identify at-risk breeds more effectively and develop targeted prevention strategies.
The role of infections and Inflammatory conditions in influencing body temperature is also being intensively studied. Scientists are investigating how bacterial and viral infections can disrupt temperature homeostasis. This includes looking at how inflammatory cytokines produced by the immune system affect the hypothalamus and can lead to a drop in body temperature. These findings could help develop more targeted treatment approaches for dogs with infections.
Finally, some research is dedicated to developing better diagnostic tools for detecting and monitoring temperature changes in dogs. New technologies, such as wearable temperature sensors and non-invasive imaging techniques, are being tested to provide veterinarians with more accurate and earlier information about a dog’s health status. These technologies could revolutionize the diagnosis and treatment of temperature disorders and improve the prognosis for affected dogs.
