There is no breed of dog that will deal with being left alone for that period of time. Unless you or someone else can make it back it at midday to give them walk and take them out, then I don't think there's really any dog that you can keep alone for an entire day.

A rescue dog would be best for you!! A rescue dog is already used to being in a kennel for log periods of time and will make a great companion. As long as you wake early and take your dog for a reasonable walk, and purchase a crate where he/she can feel safe while you are at work I don't see why you can't have a dog. Many homes have dogs where the doggy parent isn't home for 8-9 hours. Just don't get a puppy!! I would recommend 8 or 9 months as the youngest. Also house trained if possible.

That's not fair to the dog. They need attention and companionship. Maybe you should consider getting another kind of pet? A cat or some fish perhaps?

I'm lucky enough to work from home now so I am here to take my Beagle out regularly and she has me to interact with.  However, years ago I also worked a 9-5 schedule and I had a dog (it was half Pomeranian and half Boxer, what a mix!), and it worked out well.  It helped that I had a fairly short commute - I would leave at 8:30 and was home by 5:30.

If you are determined to get a dog with your schedule, here are some tips that can make it easier:

1. Talk to people at a rescue center like the SPCA.  While dogs generally want companionship from their people, some breeds are more dependant on interaction than others.  The expert at t he SPCA where I got my Beagle said she would not do well in a home where she was left alone for long stretches on a regular basis.  If my job situation were to change now I would have to find a dog walker to spend time with her.  On the other hand, the other dog did fine.

2. Consider setting up an area in a room for your dog rather than just a crate. This would require trial and error, some dogs are better off with the security of the crate, but with my first dog we set her up with a room instead.  We used a baby gate to close off one room that we puppy-proofed (nothing in there that we would be heartbroken over if it was chewed) and we put her food, water, and toys in there as well as a dog bed.  Having some space to play can help.

3. If your commute adds up to a lot of time on top of the 9-5, look into the option of getting a trusted friend or a recommended dog walker to come over, take your dog out for a good walk, and play.

4. Most importantly, don't phone it in when you're home.  Some days when I got home, I was tired but my dog was happy to see me and needed play and exercise time.  No matter how tired I was I had to commit to taking him out as soon as I got home and going for a good, long walk.  I made sure he always got plenty of outings whenever I was home, and I always made time to play with him so he didn't get depressed or destructive.  Also, it was important to take him out for a decent walk in the morning before leaving for work - with my current Beagle, I take her out for a quick pee at 6:30 and take her for a real walk a  little later when I'm fully awake, but with my first dog it was necessary to get up earlier to give him a good stretch before leaving him for the day.

The more time you can spend with your dog, the better.  However it certainly IS possible to manage a 9-5 schedule and a dog!  Just remember that if you get a puppy you'll have to expect accidents for awhile, so you might want to wait until you can take some vacation time OR get an older dog that's already housetrained.

Good luck!
