How many dogs are enough for you?

I would have to say that it depends on the space. In the house we live in, we do not have a lot of yard space, so one dog is enough. She also has more energy than I can handle. She has the amount of energy as about 3 crazy dogs put together. I also think that it really depends on the size of the dog as well.
When I was younger, I always wanted 3 dogs. Then, it went down to 2. Now, I never want more than 1 dog. lol. Perhaps if I had more space and not such a crazy dog, I would want more than one.
