For one, we can let her out back and she runs out there and gets to business. Sometimes she'll bark at a squirrel or an imaginary squirrel first, and that's fine. It genuinely seems to be keeping them away. But then she poops or pees, and then she performs the other function as well, so you get what we refer to as a "twofer".
This was not always the case, but either it's been too cold or Elka is growing up. She also used to, when turned out back without a leash, think it was obviously playtime and just gallop around in big circles. Or, if you stayed inside, she would bark at the house because you clearly had committed a grave error.
Of course, when it's not-winter we'll be taking her outside the fence again for her "business", not just letting her loose to poop willy nilly in the play space. When the thaw happens, we pick it up and rake things over and it rains a bunch besides. But perhaps the twofers will continue, even on leash?
