If you've read through all these points and now realize that you don't have the time, money, or room for a dog, don't despair! There are other options for you.
Have you ever considered volunteering at an animal shelter? The dogs at these facilities are always looking for loving people to walk, brush, and play with them. You'll get all the benefits of owning a dog, such as companionship and affection, but you won't be responsible for round-the-clock care.
How about fostering a dog? If your long-term plans aren't conducive to owning a dog, but you're still yearning for one, consider a foster program. If you meet the qualifications, you can take a dog in temporarily, until it is placed with another loving family. There are foster programs for shelter dogs, breed rescue groups, and service dogs. The plus side is you are providing a safe environment for a foster dog. But beware...oftentimes it's very hard to see your new friend go.
