I am thinking about getting a doberman in the future and have done some research on the breed but I am still on the edge about getting one because of my limited experience with dogs and the size and strength of a Doberman. As much as the type of dog is appealing to me, i fear that if it goes wrong things become more dangerous than if i had gone with a smaller dog. I have had a mini australian shepherd in the past who was quiet, and gave me no issues at all. How similar will it be to train and own a Doberman? Another concern i have is that i will successfully bond with the dog, train him, and it becomes a loving member of the family, but doesn't do well with guests and strangers. As much as i want a dog i dont want him to interfere to much with visitors and i've heard this can be an issue with dobermans because they are protective. Lastly, can this dog be one that is a family dog rather than a working dog or guard dog and can dobermans be good with children? Any advice helps, thank you.
