I agree that there are lots of different ways to keep dogs happy and fulfilled. Training is hugely important for mental wellness, and we used to take Maddy to doggie daycare a lot, too. It was AWESOME for a super-energetic, curious young dog like her. And not to say off-leash tramping around in the forest is without risks either; we see a lot of wildlife and there are traplines around here. It's just an alternative that works best for us right now.
