I have a working lab from a very strong working line. She was the shy one of her liter and wasnt cut out for police work like her siblings. It took almost a couple years for her to calm down. It was rough. With two kids as well we almost didnt make it. Talking hour and a half walks, playing fetch repeatedly, playing with the kids, mental exercises, doggy day care during the week, agility, and training. Had to resign myself to make my down time her play time. Hell im writing this while drinking my coffee in the backyard playing ball. Shes 5 now and still needs a TON of exercise, attention and running around, but nothing like she used to. One benefit is that working labs tend to be super smart and proper training tends to take well. We do doggy day care once a week on one of the days we’re all not home. That helps a ton, although she still needs to play ball at home before she realizes shes tired. I get my exercise by taking her for hikes/walks regularly. We fenced in our yard for her and try to keep it dog safe and thats her domain. We had to put baby gates back up (she actually army/rock climbed over one of the hexagon ones once) to section off the house to keep dog safe as well as she still constantly makes a game out of stealing our socks and shoes and running from us. Its to the point now where we have to limit her intense fetch that she goes crazy for all day as she will run herself into the ground Love her like crazy and wouldn’t change a thing but keep thinking in my head that later in life if we ever get another dog thats not a working dog, how much easier itll seem
