Pets play an important role in our lives today, as members of our families. In history, those same animal types were used for different purposes. The luxuries we give our pets today originated from need of them in history. I am a pet groomer, and would like to know some history relating to my profession, but am unable to find a satisfactory quantity of infomation. What historical events were caused by these pets, the use of them and the methods of maintaining their health?
