My dogs can easily get the exercise, without my having a specific dog walking routine.
Example of a random day - Wake up in the morning, ignore excited dogs. Go make coffee and step outside to a glorious (or rainy) day. Dogs follow, but have to sit at door and wait till I say ok before stepping out. Throw sticks for dogs to chase while having coffee
Go down to the forest to mark trees to be cut, dogs follow down, sniff for rabbits, chase and bark at forest sounds and then back home. Tree cutting guy comes, greeted by everyone including dogs. Dogs follow again as we go down to forest to discuss, same dog routine, interspersed by each dog inserting themselves for extra touches by strong, manly tree-guy.
At home, prepare dogs brekker. Dogs sit and wait nicely till i say ok, and then gobble up their food. I get to work, dogs lie down close by and nap, tired after the excitement of the morning. At noon, walk to the village to get eggs, as hen-lady will be in her house preparing lunch. Go down the path, chat with neighbours, dogs with me saying hello to neighbouring dogs. Practice recall and play chase-the-stick. It takes 30 minutes or so, a nice downhill and a strenuous walk back.
Return home, Make myself a simple lunch of an omelette. Eat and train dogs on the wait command as I feed them some morsels of my meal. Clean up, get garbage together to drop off at garbage collection boxes, half a mile away, dogs come along.
I continue work, dogs shooed out where they play and sleep. In the evening I work on the garden, dogs around, girl dog helping with the gardening. Go down to the forest to see how the tree cutting is going, dogs come. Then walk to friend's house for an aperitif, dogs come along and meet up with friends dogs.
Evening meal for all, time on the terrace, cuddles and a quick groom for ticks etc., and then bed.
Would say the dogs got plenty of mental and physical stimulation, easily 2 hours of walking with us, combining all the activities. With regard to mental training, they get it interspersed throughout, without setting up a specific training session. They are also expected to show good manners throughout the day ( e.g., not jumping when greeting neighbours, sitting down nicely if they want to be touched) and are corrected when not. This is a day when the dogs are not formally exercised. On the days we do focus on the dogs specifically, we take them swimming, out for long hikes and they love it! But to somehow think that a dog with a daily routine similar to ours is neglected, is bonkers
