📈 Why Monitoring Vital Signs Matters

Changes in vital signs—such as temperature, heart rate, and respiratory rate—are often the first signs something is off. Tools like TailVitals help pet owners monitor these changes at home, offering early detection before visible symptoms appear.

Normal Vitals in Dogs and Cats:

• Temperature: 100.5°F – 102.5°F

• Heart Rate: 60–160 bpm (dogs), 140–220 bpm (cats)

• Respiratory Rate: 10–30 breaths per minute

If your pet's vitals fall outside these ranges, consult your veterinarian.
