You're awesome. I volunteered at a pet shelter and the biggest mistake people make is not researching what breed best fits their lifestyle. You seem like you've really thought about being a true responsible pet owner. This is good.

I say you adopt. Check out the shelters in and around your residence. I know they have a bad reputation and most people think only gnarly, aggressive and flea infested dogs end up there but that is so far from the truth. I don't know how kill shelters work, I volunteered at non-kill shelter, but aggressive and unstable dogs were fostered and trained. People would walk in expecting to see these ill-behaved dogs with aggressive tendencies but what they found most times were somewhat unruly (like they weren't told not to pounce on people when they were happy) but most for the most part sweet, fun and potty trained dogs. At times really special dogs came in who could do an array of tricks. Some ended up being therapy dogs and service dogs. Others joined the police force. So don't believe the stereotypes of shelter dogs. Most are really awesome fur pals who can certainly make awesome fur kids. A lot of those are already trained because most times dogs are surrendered rather than found homeless. For whatever reason their previous owners just gave them up, but this is a plus because it means you don't have to go through the hassle of training them (especially if you're busy). If you're looking for a specific breed ask about breed specific rescues. I always advocate adopting over buying from puppy stores. I have one little dog that was purchased at a pet store and his health issues are off the charts. :( Most of these dogs are irresponsibly bred. One more thing, the dogs you adopt might seem expensive. The reason why they do this is because if they're no-kill they need that money to fund the shelter and because the most expensive the price that a person is willing to pay for a shelter dog the more likely that they are to be a good pet owner.
