German Shepherd
German Shepherds are another breed of dog used in police and military units, and these guys may be the most effective breed out there for this particular work. Precision training is their specialty, their selective smell the reason they work in explosive and drug detection. This breed became famous for their intelligence, and this is the reason they are bred today. After testing and training it was discovered that German Shepherds obeyed the first command given to them over 90% of the time, and executed simple tasks after five or so reps. It’s no wonder they made #3 on our list!

Poodle
The amazing intelligence of Poodles comes as a surprise to many as they’re more known for their crazy hairstyles opposed to their IQ. When the Poodle was tested, toy, mini and standard were all included in the study. Their obedience and memory afforded them cream of the crop marks. Their sharp working sense makes them very responsive to commands, while their webbed feet make them superb swimmers. Poodles love water, and thankfully their liquid-resistant coat serves them well in the rain. This majestic breed is also extremely athletic.
