At our SPCA, there are 5 BC/GSD mix puppies, and my family has decided to get a dog, I am just wondering if I would be able to give the dog enough exercise as I know both of these breeds need a fair amount of exercise. I am willing to walk/jog for 30-45 minutes in the morning with it and it would be home from 8-12:30ish, and I would come home check on it and play for about 15-30 minutes. It would then be home from 1:20-3:20ish, when I would come home. I would play/train for all together 1-2 hours each evening and go for another 30-45 minute walk, would this be an adequate amount of exercise for this kind of dog? Thank you!
