Hey Guys. I need a little advice. I have done a lot of research on these two dog breeds and I know they are very energetic, and require a lot of training. My question is which one would you suggest I buy. I am 24 years old, work 8 hours a day in Southern California. I want a dog that can run with me in the mornings and the evenings. I run an average of 13 - 15 miles a day, an hour in the morning, 30 minutes in the night. Which dog do you believe can handle that? or handle it better? I want a running buddy! Secondly, I work during the day 10am - 6pm. I live a fairly large apartment, but no back yard. With either dog, do you think it would be okay to leave him alone in the house given that he will be given that much exercise a day with training, and play when I am home? Which would be better? Thanks!
