Multiple dogs, how?

How do people deal with multiple dogs?

I've been trying to wrap my mind around what my life would be like if I adopted another dog. I'm having such a difficult time imagining having enough time to care for multiple dogs.

At this time after dinner I spend about an hour grooming Marley. This includes combing out her ears, brushing her coat, checking her nails and brushing her teeth.

After our grooming session I spend some time playing with Marley. I usually attempt to play fetch; however she prefers hide and seek. We also do some training during this time.

After this I will give her a chewy and I'll spend some time with Bob. This involves grooming him and cuddling.

I have such a hard time visualizing how I could add another hour to my day to spend grooming an additional dog. How in the world do people with multiple dogs do this?
