In Mila the 6-year-old Doberman, which three problems were identified as the main issues?

• A. Bradycardia, hypothermia, increased CRT
• B. Tachycardia, hyperthermia, normal CRT
• C. Hypertension, tachypnea, loud murmur
• D. Bradycardia, hyperthermia, decreased CRT

Answer: (A)

When a dog is critically ill, clues to poor tissue perfusion come from how the heart is working, how the body temperature is, and how quickly blood returns to the capillaries. In Mila, the combination of a slow heart rate (bradycardia), low body temperature (hypothermia), and a prolonged capillary refill time indicates that the heart isn’t pumping effectively and tissues aren’t being perfused properly. Bradycardia can reduce cardiac output, so less blood reaches organs; hypothermia often accompanies shock and decreased metabolic heat production; and increased CRT confirms that peripheral tissues aren’t receiving adequate blood flow. Together, these signs point to a circulatory compromise that needs urgent stabilization.

The other patterns don’t fit as well. Tachycardia with hyperthermia and a normal CRT would suggest fever or heat exposure rather than shock with poor perfusion. Hypertension with tachypnea and a loud murmur implies a different cardiac issue, not the marked perfusion deficit shown by this triad. Bradycardia with hyperthermia and decreased CRT would be unusual because hyperthermia doesn’t align with poor perfusion in the same way, and decreased CRT would suggest better perfusion, not the compromised state indicated here.
