My family and I recently lost our bullmastiff female. We love the breed and plan on eventually having two big dogs in our household....a doberman and another bullmastiff (eventually). I have read a lot on the doberman breed and understand the breed requires a significant amount more exercise then a bullmastiff. A freind of mine advised me the breed was very hyper. I know it is protective, I know to socialize the dog when it is young with other dogs and getting it acclimated to young kids, and that you have to stay on top of good, stern training program.....no problems there. Also, I know different dogs have different personality.
My question is, is the doberman breed hyper and is it suitable to be an indoors dog about 95% of the time? My wife runs 3 miles per day and would take the dog on most of her runs.....it would play in the yard....go on trips to the park and dog parks, freinds pools, etc. etc. etc. but of course their are plenty of times when the dog may not get out as much. I do not know anyone that has a dobey so it I am asking advice from y'all. I live in the Dallas-Ft.Worth area.
