What if my doberman is alone for 6 hours?
I'm planning on getting a Doberman in the summer. I have done my research and it seems as if I had to choose between the Doby and the Shepherd, but the Doby gets the edge.
I go to school during the regular school year from 7-2. Would my doberman have a hard time doing nothing? I will walk it in the morning before school to get it tired and in the evening, each walk about 45 minutes. I will be really loyal and nice. All it takes from the Doby on his side is the patience.
Any experiences?

No the dobe won’t be patient it will be BORED. And that is 7 hours. A 45 minute walk will definitely help. A puppy cannot go 7 hours waiting, nor do 45 minutes in the morning. This is an active breed both in exercise and mental stimulation. They are also a very mouthy breed, you will likely come home to chewed things and a very energetic dog. As well, they are a slow maturing breed.
Is this your first dog? If you do want a dobe, I suggest adopting one that is 4 years or older.
ETA: do not leave your dobe(or any dog for that matter) outside while you arnt home. ESPECIALLY if it is because the dog has high energy. They will destroy the yard, piss off the neighbors will barking, they could be stolen, poisoned, jump the fence, etc. Not to mention dobes are velcro dogs and do not like being left outside on their own.
