When it comes to the most alert dog, it must be the German Shepherd. The German Shepherd is very smart, ranking first in IQ, and alert. If you want a dog to look after the house, then the German Shepherd is a good one. As long as a thief sees a German Shepherd at home, he will definitely stay away.

German Shepherds are also very popular in the military and police fields and are widely used for anti-drug, escort and reconnaissance tasks. German Shepherds are also very easy to train. As long as they are trained with dog snacks and chicken jerky, the German Shepherd will be very serious! If the owner does not know how to train his own pet, he can go to a professional pet school.
