Just to float it out there, 2 dogs really don't take up more time than 1 - I had 1 dog at a time for years, and then got two because they showed up on my doorstep and I couldn't turn them away. I don't feel like I spend any more time with them than I did with the single dogs -- - they're almost always together so if you spend time with one, you're with the other too.
The only trouble is that they gang up and outsmart me from time to time
