It's rare to see a Doberman where I live, there are two a couple houses down from my mom. Beautiful red male and black girl, however they do not ever leave their yard and if they are outside and a leaf blows by they go off like crazy and do not stop. They are good looking dogs and well taken care of, but from what I perceive meant more as property protection than hobbyist pets. A tiki bar I worked at had a giant white Dobe that was a semi regular, very very sweet gentle giant. An ex of mine was a pool boy and one of the houses he serviced were BYB breeders with a red and black pair, I never got to meet them but he would go on about how enthralling they were. Other than those few occurrences, I can't think of a single other time I've seen any.
When I take Brinks for walks, it's apparent he's a mutt but no one is ever really sure of what. People that are more familiar with shepherds comment that he's Shepherd, and people more familiar with Dobes see the Dobe. We were recently at the sand bar this past weekend and the neighboring boat had a Shepherd of some sort, the guy asked if Brinks was a "really skinny Shepherd"
it kind of hurt my feelings because yes he is tall and lean like a Dobe but he is by no means small at over 90 lbs and there is not a rib to be seen!
I just remembered my SO dad had two male pups years ago before I ever met him and ended up rehoming them... he's not a responsible person and YIKES! Also their family friend (who is a great dog owner) had a few of them over the years. Fairly recently the last one passed on and he hasn't brought himself to get another yet, though he does enjoy coming over to see ours.
I forgot to add that I see quite a few Great Danes. Our neighbor down the street always has one and always adopts. I've seen them frequently on the beach, in the pet store, and at the same tiki bar I worked. There's a lady that has five she takes to the dog park, she drives an Excursion just to have room for them all! Lovely dogs.
