Would it matter if the dog was an older dog or would you prefer a puppy? You should look around in the animal shelters i cant give you any links to them but loads of ppl here can, i think maybe an older dog would be more suitable seeing as you work and it will be left alone for a while during the day so it should be too hyper like a puppy would be, im not sure where you are from but theres lots of ppl here with links to different animal shelters i think the only one i know is petfinder
