Dog versus human

Here are some interesting facts:

1. Body Temperature

Canine normal body temperature is between 38° to 39.2° Celsius.  The commonly accepted average body temperature in humans is 36.8° Celsius.
2. Respiratory Rate

Dogs: 10-34 breaths per minute, unless panting.  In human adults over 18:  12-20 breaths per minute.
Normal respiratory rates are assessed when the dog/person is at rest. Pain, heart or respiratory problems, heatstroke will usually increase respiratory rates.
3. Heart Rate

Dogs: beats per minute: 60 – 100 for large breeds, 100 – 140 for small breeds.  In human adults 60-80 bpm.
Larger dogs have slower rates than small dogs, and dogs that are in good physical shape will have lower heart rates than dogs of similar age and size who are not physically fit. Puppies typically have higher heart rates, up to 180 bpm; this is normal up to one year of age.  Normal heart rate in children is variable and depends on the child’s age.
4. Duration of Pregnancy

On average, canine pregnancy lasts 63 days.  In humans: 9 months say 274 days.  Elephants: 624 days.   The larger the animal, the longer the gestation period.   
5. Number of Teeth

Puppies have 28 teeth; adult dogs have 42 teeth.  The loss of baby teeth usually starts at about 3 months and ends by 6 to 9 months.
A child has 20 baby teeth and they start falling out at about age 6.  An adult has 32 teeth including wisdom teeth.
Silly question: do dogs have wisdom teeth?  I must ask our vet.

Ah well, WW, their sense of smell and hearing are far superior to ours.
