I have a puppy collie/Shepard mix that is about a year old. Do you have any tips/suggestions? Do you regret getting such a smart dog in general?
Genuinely curious - is there any reason why person would potentially prefer a less smart dog? I always thought that, the smarter they are, the better companions they can be, so your comment got me wondering.
High energy dogs get bored, frustrated, or destructive when not given enough exercise. And a high intelligence just means they're that much more creative in finding ways to amuse themselves (that probably won't amuse you...).
Additionally, part of what makes dogs such amazing companions is their empathy for humans not just intelligence. The current dog of my aunt and uncle is pretty dumb, compared to the previous one. But he loves people, cuddling, and he's super mellow.
He still needs to be walked 3-4 times a day, but not particularly long and he's perfectly happy just chilling and lying next to you all Saturday. That fits much better into less active lives than something high energy that needs to run 10-15 miles a day...
