    11. 11. ALERT DOG <ul><li>TAIL & EARS POINTED UP </li></ul>
    12. 12. AGGRESSIVE DOG <ul><li>HAIR, SHOULDER,RUMP RAISES & LIPS DRAWN BACK </li></ul>
    13. 13. FRIGHTENED DOG <ul><li>EAR FLATENED AGAINST HRAD REGION TAIL DESCENDS UNTIL ITS BETWEEN THE LEGS </li></ul>
    14. 14. DEFENSIVE
    15. 15. SCENT COMMUNICATION <ul><li>VERY POWERFULL </li></ul><ul><li>USED FOR PATH FINDINGS </li></ul><ul><li>DOG:-repeated urination </li></ul><ul><li>WILD DOG:-leave their droppings </li></ul><ul><li>Glands on the feet skin lips & anus are modified secretion </li></ul><ul><li>ALL CANINES HAVE A SCENT GLAND </li></ul><ul><li>(marked by black spot on the upper basal half of tail) </li></ul>
