I wouldn’t have said that daschunds were exactly easy for first time owners.
They are known not to be the easiest to house train for example.
Have you thought of adopting an older dog?
Mine don’t run off as they are trained to command but the male does try occasionally. The female sticks so close that we trip over her constantly!
Their intelligence can be a blessing and a curse when training them. They can be quirky. I would say that they have to have a lot of energy, time, care and attention spent on them as puppies to stop them developing bad habitts like constant barking.
Long haireds don’t shed a lot. Or smell strongly of dog. Ours are very neat eaters.
They are fine on rough terrain. Some people will not agree with this but we don’t wrap them up in cotton wool. My personal view is that the fitter they are, the stronger the muscles that support their backs. We obviously try to avoid a lot of jumping from heights.
Up to you op but my advice for a first time owner would be to adopt an older calm dog from a shelter who in effect teaches you about dog ownership.
Don’t focus on breed but character.
There are plenty available if you are prepared to wait for something suitable; they are given up because of death, divorce or debt. They don’t all have terrible issues by any means. But they need time to settle in and a degree of patience. And an older dog may incur more vets fees.
Also, sorry, I agree with pp that terriers can be s bit tough for first time owners but they are well suited to a rural setting.
Good luck!
