Hello every one I have thought about getting a dog but I don't have much yard I just have a deck although I'd run the dog for about 45 minutes every day I don't want a little terrier or jack Russell or Maltese I want a dog that will run with me and is medium size my only concerns are that I don't have much yard and Of course I have to work and will be at home every once and a while so please please write down some dogs I should consider just want them to be medium to large dog that can run but when at home just dozes off and stuff so please write down some thanks a lot.
