Personally, I don't feel a Doberman was bred to be raised without the opportunity to run and explore...and is not a breed condusive to apartment living....jmho
If there is absolutely no way a human can live in any other situation, and they are positive they want a dog, I would look into a breed that is easily more adaptable to apt living..like a Yorkie, or even a Bulldog..
That is not to say a Doberman is not adaptable to just about any situation, but in that case an older, more calmer, settled and house broken Dobe, would be more suitable..way past the puppy stage..
Sometimes it is harder to put their best interest ahead of ours, but nevertheless it needs to be something taken into consideration, when choosing a dog..
There are alot of people in New York City that live in high rises in Manhatten, that have Dobes,(besides other large breeds) and they do have alot of dog parks there, but it still doesn't change the fact that Dobes just were not bred to be "couch potatoes", not meaning there is anything wrong with that, it just isn't what they were bred to do as a breed..So when acquiring a dog a person should consider their lifestyle, no matter how much they like the looks and aura of a certain breed...
I got a call from a gal that asked me to help place her boy of 7 yrs, because the apartment bldg she lived in was sold to someone that had a size limit on the dogs that lived there. (25# and under)...otherwise she would be kicked out if she didn't get rid of her dog..She said she loved her dog and couldn't afford to find another place, and whatever her reasons, were, she imho should have never moved there in the first place without some kind of guarantee that even if the place changed ownership she would be grandfathered in, ...long story short, her dog found a good home, but the point is even if you do live in a certain apt bldg, what's to say the landlord won't decide to change their policies, etc.? Condos are probably a little better, but not much, cause they have rules you have to abide by too, that may not be perfect for owning a Dobe...Just saying...
The reality of some situations in our lives may not be easy to accept of deal with, but it still doesn't change the fact you have to put the best interest of that innocent dog ahead of what we want for ourselves..We have our abiltiy to reason, they don't, they just trust us to do the right thing for them....
