commonalities of all mammals
Commonalities of All Mammals
  • Have mammary glands
  • Have a single lower jaw
  • Have hair
  • Are endotherms
  • Have a diaphragm
  • Have a four-chambered heart
smell
Smell
  • Excellent sense of smell. Helps them to sense prey
slide5
Eyes
  • Eyes in Front of Head
    • Allows for depth perception
whiskers
Whiskers
  • Sensitive whiskers
    • Whiskers work with air currents to pinpoint where prey might be
    • Touching whiskers closes the dog’s eye for protection
eyelids
Eyelids
  • Nictitating membrane
    • acts as third eyelid
slide8
Feet
  • Walk on toes at 90° angle
  • Paw pads for protection
maintaining body temperature
Maintaining Body Temperature
  • Main cooling is from panting
teeth
Teeth
  • 42 teeth in adult
  • There are four types of teeth.
    • Incisors are the primary biting teeth.
    • The canine teeth bite and tear food.
    • The premolars shear, grind and mash food.
    • Molars are responsible for the most rigorous chewing.
reproduction
Reproduction
  • Gestation period is 63 days
  • Only goes into heat (estrus) twice a year so can get pregnant only twice a year
  • Has an average of 6-8 babies at a time depending on breed
smell1
Smell
  • Excellent sense of smell. Helps them to sense predators

Eyes
  • Eyes on sides of head
    • Allows for two fields of vision – looking for predators and escape route simultaneously
    • Poor depth perception
whiskers1
Whiskers
  • Sensitive whiskers
eyelids1
Eyelids
  • Nictitating membrane
    • acts as third eyelid
slide17
Feet
  • Flat-footed with no

foot pads

    • Use claws for traction
maintaining body temperature1
Maintaining Body Temperature
  • Large ears for temperature control and hearing
teeth1
Teeth
  • Two pairs of incisors in upper jaw. One smaller pair behind the larger pair
  • 28 teeth that grow continuously
  • They have molars and premolars too!
reproduction1
Reproduction
  • Gestation period is 31 days
