Whichever one fit the lifestyle of myself and my current animals.

We have always adopted puppies due to the fact Simba likes them better. He's a lot more tolerant of a small obnoxious puppy than he is a large obnoxious dog. Simba is turning 8 this year and the girls (1 year and 2 years) keep him going.

When I'm too lazy to deal with a puppy in my future, I will more than likely be adopting adult dogs.
