Bacterial infection is a Streptococcus infection that can cause illness in dogs. Usually, puppies and older dogs are most susceptible to developing this disease because their immune systems are not fully developed or weakened respectively.

Generally, the dogs are curious and amused by nature. Every dog is different in behavior. Some dogs are fearful in behavior, and others are more inclined towards fear. Dogs are highly communicative to their surroundings, but often they become anxious and worried about some situation.
