I’m not young and active enough for one of these animals but for an active owner with a good understanding of these fine dogs, they are great. Properly trained, they are good with active kids and very protective. A smart dog.
At my age, a French BG is perfect. Smart as any dog but more laid back. Must have exercise but nothing near a German Shepard or similar.
What is a French BG? I breed German Shepherds, but not the kind that is so intense you’d need to run them miles every day. However, there are definitely many like that and people need to be aware that the breed can be fairly active.
