Answer: German Shepherd Dogs
Explanation: I think German Shepherds make amazing pets! They're the 3rd smartest dog breed and they're loyal and protective. They can be a tad bit aggressive, but with proper training and socialization, they can be perfect family pets. They are great working dogs as you can often see them working as police dogs, guide dogs, therapy dogs, search and rescue dogs, and more because of their trainability and eagerness to please. :)
