well here's something from me. i am a security guard and i work various hours, could be anywhere from 8 to 12 hours. days, nights the works. i own 3 sibearian huskys who get there required exercise and are in verry good health. the key is management and planning however when they are a puppy they require alot of attention. training and cleaning up are 2 main things you do with puppys
well i hope you can make the right decision and if you do end up getting a dog then good luck
