Comparing the intelligence of female and male dogs
The hypothesis holds true: female dogs are more intelligent than male dogs.
Dogs are often called "man’s best friend". They are very intelligent and help us to perform many tasks. Dogs have helped us hunt for hundreds of years. Farm dogs help farmers round up sheep or cattle. Security dogs help guards to perform their duties. Equipped with aa sharp sense of smell, dogs help to sniff out drugs and contraband items. They are often used at customs checkpoints, to fight the battle against smugglers as well as terrorists. Dogs are also trained as guides for the blind.
For more reliable results, we should use a larger sample of dogs.
Also consider using other breeds of dogs for this science project
Modify the experiment by making the dogs perform other tasks.

Take extra precaution when dealing with animals you are not familiar with, to avoid getting bitten. Although they are extremely intelligent, German Shepherds can be temperamental and unpredictable if not handled properly. Make sure that the trainer or owner handles the dog at all times.
