If you want to take care of a dog and want to be adopted by a dog, I think it is a good idea, for you, for the dog. To decide to have a dog it's a very important decision, with pros and contras. A dog is another member of the family, 100%, till his death. I am sure you know all this but it is important to remember it. Yesterday I was thinking about my dogs: thanks to them I am in good shape, physically, I am alert, walk a lot, take air. The pros to have a dog are infinite, dogs are teachers of many many things, they are really, really amazing. But you have the other side of the money, you can not travel as you wanted, you sometimes have difficulty finding an apartment that accept dogs, things that for me are less important then the benefits to have a dog: a good friend, a good company and a teacher.
