I'm always interested in hearing all the misconceptions people have about not being able to own pets. Recently I was speaking with someone who said he just didn't have enough time in the week to devote to a dog. That it didn't seem fair to a dog to just sit around in a crate all day.
I think a lot of it is just our own human guilt and perceptions of what our dogs need. I know we all have images of how our dogs would love to have exciting days every day, but I don't think that's reality. Dogs still need time to sleep (I've heard they sleep as much as 14-18 hours a day!) and as long as they get exercise in the morning and evening, are mentally stimulated and properly socialized, we shouldn't have to feel guilty about leaving them while we're gone. We make sure the time we do spend with them is quality time.
I know a lot of us sometimes use dog walkers and doggie daycares for extra energy mid-day breaks, and I'm always partial to adopting a mellow Elderbull who would love the time alone during the day to sleep.
Though if you don't have other time in the evenings and weekends to really work with and spend quality time your dog it might not be a good fit.
What does everyone else think? How much time does a person really need to make sure their dog has a fulfilling life?
