One night, the dogs attacked a suicide bomber who was trying to enter the camp. The bomb was detonated, but luckily none of the soldiers lost their lives. Unfortunately, Sasha the smallest pup lost her life, while the other two dogs, Target and Rufus, were nursed back to health. With dogs, a little love goes a long way.
Dogs learn more from visual inputs rather than audio. Try to associate an action to your commands. This also means that when communicating with your dog, it should have your complete attention.
Spend some time (at least half an hour) everyday with your dog. This does not include the time you take it for a walk, but are glued to your phone. Spending time means the focus ought to be on the dog, do things it enjoys. This could be chance for you to get to know him better and work on your communication.
Also, pair basic verbal commands with specific actions. Always communicate with these; as far as possible, everyone should use the same set of commands.
While telling a dog not to do something, it is important to suggest what it is supposed to do. Reward him for good behavior, irrespective of whether you asked him to perform a task or not. This will ensure that he repeats that more often.
