I would guess that there may be a bit of an adjustment period getting her house-trained and all the rest, and you might not be able to stick to your ideal schedule. Your bike will wait patiently for you, but a dog won't.

In addition to what MartianDestiny wrote, if daycare is appropriate for your dog, then that might help with providing a lone pet with opportunities for socialization and exercise. We take our dog to daycare twice a week and it's been great for him. I don't have to spend a ton of time tiring him out on the days that I have him at home, and the people at daycare have done a great job of reinforcing good behavior. Another bonus is that they have a kennel-free overnight service, so if we are traveling we know we can leave him with people we trust, in an environment where he is comfortable.

I will emphasize that there was a bit of a process to find a daycare that was a good fit for our dog. For one thing, you may need to get some vaccines that are over and above what is required by your municipality, depending on where you are. Could mean time out of your schedule and $$ out of your wallet for extra trips to the vet.

We did trial days at two places that didn't work out. At the first one they kept the dogs at a high level of energy to tire them out, and Gordy was pretty depressed for several days after that experience. The second one, the owner wanted to observe him first in a kennel which he did NOT like, so he was distressed and barked for two hours straight (he's not much of a barker ordinarily) and she felt he was not a good fit for her other dogs.

Third time was a charm: they do a great job of managing the pack energy a la Cesar Milan, a couple of treadmills so that the dogs can get some exercise inside during the long winters here. It was a great fit from day one. But it really was a process of learning about our dog and what he needs, and that all of these different places had something different to offer.
