Thanks. Great advice! I will research more of what breeds suit me best. I might try volunteering at the shelter so I can get a better feel for what the dogs are like.Well, if you're adopting from a shelter, you're likely going to get a mix. I think the Lab mixes or Golden mixes are a pretty safe bet all around, typically. Like Parus mentioned, you might want to avoid certain breed mixes that are known to have traits you might find undesirable. Huskies are notorious escape artists, howlers, and will run for miles happily without you, so that might not be a good fit for someone who wants to do off leash things.
And, of course, if you're renting pit mixes might be banned in your apartment complex, so think of that.
When you're adopting an adult, though, look at the individual dog. I would go with a dog that has been fostered for some time so the foster can tell you more about their personality.
