I agree with adopting an older dog from a reputable rescue group. I also agree with the crate training. If you don't want to crate, then at least get some child gates and create a small area (or bigger crate) for them when you are gone. Some dogs will get very stressed out repeatedly searching the house for where you are at.

We've been doing retired racing greyhounds for years and certainly recommend them. But for a first dog, adult rescue may be the best option.
