Dogs usually send warning notes in the form of non-serious bites before any serious
attack. If you step over a dog who’s resting or try to move a dog off the bed for any
purpose you should know what to expect.
Security and Protection:
Some dogs feel insecure as a result of some of human actions like invading a
dog’s territory, riding on his back like pony, showing off with ferocious displays, blowing
puffs of air in his face, taking her food or disturbing a mother dog and her puppies. They
believe these human actions can cause them harm.
It could also be from being continuously chained. Continuous chaining of dog can cause
physiological problem and thus the affected dog may not know how to behave when it’s
released. So in other to protect themselves, they result to aggressive acts like biting.
