My daughter brought home a dog she was supposed to care for but now she moved off to college out of state. So now dog is mine. I have fallen in love w him but I would never have procured a dog. I have 2 cats. I did a canine DNA test on him and he is German shepherd, Australian cattle dog, lab, and Staffordshire terrier mix. Mostly German shepherd and cattle dog according to test. I'm 52 and work 12 hour shifts 3-4 days/week and am sedentary otherwise cuz I'm tired. I play fetch w Zuko but we otherwise stay inside. He stays in fenced in back yard while I'm at work. He is 1 year 4 months. I feel like I'm to old and lazy for him but we really bond well. I have some health problems that prevent me from exercising him as much as research says for the types of dogs he's comprised of. What should I do? Give him to someone younger? But I love him. Very distressed! Please reply!
