Reference ranges for the vital signs of the dog from the MSD Veterinary Manual tables, which are adapted from *Dukes' Physiology of Domestic Animals* [1][2][3], compared with the vital-signs chart of the UC Davis California Veterinary Emergency Team [4].

## Reference ranges

| Parameter | Dog | Source |
|---|---|---|
| Rectal temperature | 37.5–39.2 °C (99.5–102.5 °F) | [1] |
| Resting heart rate | 70–120 beats/min | [2] |
| Resting respiratory rate | 18–34 breaths/min | [3] |
| Estimated blood volume (used in transfusion calculations) | 80–90 mL/kg | [5] |

## How the references compare

Published reference ranges differ between sources. Each range below is printed as its source gives it; °C values marked * are converted from the source's °F.

| Parameter | MSD Veterinary Manual [1][2][3] | UC Davis CVET [4] |
|---|---|---|
| Temperature | 37.5–39.2 °C (99.5–102.5 °F) | 100.0–102.8 °F (37.8–39.3 °C*) |
| Heart rate (beats/min) | 70–120 | Small dogs 100–160; medium dogs 60–100; puppies 120–160 |
| Respiratory rate (breaths/min) | 18–34 | 10–30 |

## Other findings in a healthy dog

The UC Davis chart lists as normal: pink, moist mucous membranes; a capillary refill time under 2 seconds; soft, non-painful gastrointestinal findings; and a bright, alert, responsive (BAR) demeanour [4].

## Frequently asked questions

### What is the normal body temperature of a dog?

The MSD Veterinary Manual table gives a normal rectal temperature of 37.5–39.2 °C (99.5–102.5 °F) [1]; the UC Davis chart lists 100.0–102.8 °F [4].

### What is a normal resting heart rate for a dog?

70–120 beats per minute in the MSD table [2]. The UC Davis chart gives 100–160 for small dogs, 60–100 for medium dogs and 120–160 for puppies [4].

### How many breaths per minute is normal for a dog?

18–34 breaths per minute at rest in the MSD table [3]; 10–30 in the UC Davis chart [4].
