Some breeds of dog are specifically bred to work, they are very high energy and highly intelligent. Because these traits have been bred into them over many generations, they need to have a "job" to do, to utilize their energy and intelligence.

For example; Rottweilers are classed by the AKC as "Working Group" and generally are well suited to perform a job or task. This may be why there are so many Rottweilers doing security and personal protection work.

Each individual dog is unique, regardless of breed. It is important to know what motivates your dog, and then properly train to utilize their unique skills.

Some breeds of dogs are specifically bred to be companion dogs. They have been bred for gentleness and docility. Because they are gentle, there is often an assumption that they do not require training. Unfortunately, this belief can lead to behavior issues and unhappiness for both the dog and their human family.

For example, Italian Greyhounds were used in Regency England as "bed warmers", to keep the bed warm throughout the night. Italian Greyhounds also tend to be very high-energy, and high intelligence animals, so they require the correct training to be able to be a good companion for their human.

Each family has unique needs for their pet companions. It is important to asses each family and it's home environment to provide your companion dog with the training and tools needed for success.
