I have gotten a few emails lately from people that should probably NOT get dogs. Even a perfectly trained dog needs to be walked 3 times per day, need medicine when its sick, and daily care and attention. So, if you aren’t prepared for that-do yourself and the dog a favor-don’t get one.
The next question is, how do you know if you are ready?
Try it out. Dogs are available…your friend has one, the shelters have some, spend some time with one and see how it goes.
