So I recently got one of my dream dogs, which is a belgian shepherd (groenendael). I realize too late that I should have gotten a shepherd later... as my other dream dog is a cardigan welsh corgi. It would have been easier to bring in a small shepherd puppy with a grown corgi, rather than the other way around. Now I'm worried I won't be able to get the corgi at all. My belgian pup has a good temperament and is very trainable, but obviously very playful. Could I still get the corgi (when my shepherd is about 1-2 years old) or would that be too dangerous for them with a playful shepherd? I worry because they'd be so small and because of their long back.
