Dogs differ in their likelihood to show aggressive behavior in any particular situation.
Some dogs tend to respond aggressively with very little stimulation.
Others may be subjected to all kinds of threatening stimuli and events, and never attempt to bite. The difference in this threshold at which a dog displays aggressive behavior is influenced by both environmental and genetic factors. If this threshold is low, a dog will be more likely to bite.
