2. German Shepherd
The second favourite dog to be owned in the USA is the German shepherd.
Intelligent, confident and brave this large dog was originally bred to work and therefore needs plenty of physical and mental exercise to keep him both happy and healthy. This loyal family pet will make a great guard dog and is very affectionate and protective of children. The thick double short coat that can be found in a variety of 11 colors will shed in season and therefore requires plenty of grooming.
