there are several breeds i'd like to own at some point, but looking at things realistically instead of just "wishful thinking" that list would get narrowed down quite a bit.
yeah, it's possible to keep large dogs in apartments or houses without a decent sized yard, but for me personally that's (a) not fair to the dog and (b) i'd want to be able to offer a breed the kind of environment and lifestyle it was bred for.
my husband likes to travel and i like to bring the dog along as much as possible, so for the next 15 years or so i'm not planning on any of the larger breeds i'm considering (giant schnauzer, black russian terrier, hovawart etc.) but instead on "big dogs in a small package", like for example jack russell or border terrier or another wirehaired dachshund to compete in earthdog trials and hunt tests.
but then things often tend to develop completely different than you planned them anyway, so i'll just wait and see. we are also planning on moving to new zealand at some point and if at all possible i'd want to avoid having any pets go through 30 days of quarantine.
