One thing to look for would be the breed that fits with yours in personality.
Let's look at an Afghan Hound.
The AKC says this: Known for being aloof, dignified, and for having a highly individualized personality,... So maybe if you are a touchy, huggy, kissy type person this dog may not be the breed for you. Maybe a better breed for this would be a Golden Retriever. The AKC says: With his friendly temperament ...
Okay that looks promising but what if you also want a dog to snuggle with on the couch BUT don't want to do a lot of exercising with your dog. Well, let's think about the Golden again because: "daily exercise" is noted with his breed. Now of course all dogs need walks and have play time but if it is in their breed make-up you can be sure that a little leisurely game of chase the rolling ball across the kitchen floor is not what is meant. So this doesn't look like a good fit for you.
