Also think about vacations, business travels (if applicable in your job), weekend nights etc. Do you have someone as a backup? We walk our dog about 4 times a day - each day...

If you don't have the time / possibilities to have your own dog, you might want to check the next animal shelter. I do not know about the US, but here they always are looking for "walkers", i.e. people who are coming on a regular basis to walk one of the dogs. So you do not (have to) take it home, but still can build a releationship to a single dog.
