Decision : to get an older dog or not ?

Older dogs rock! I'm NOT a puppy person whatsoever. We have two adopted rescues, Maddie and Kramer. Maddie was 2-3 when we adopted her four years ago, and Kramer was about a year old when we adopted him earlier this year (we were told he was older and were shocked when we found out he was still a baby!). In the past, I've adopted a 4 year old lab (he lived to be 11 yrs. old) and also a 9 year old Golden (who lived to be 17!), as well as several middle-aged to senior boxers (4-9 years old). We've also fostered senior dogs, and I LOVE them! The worst dogs we've had at the beginning are a young beagle/bassett and a 4-5 month old black lab (although the black lab turned out to be one of the BEST dogs we've ever had, once he matured, around age 4 and who lived to be 14.5 years old!).

I'd aim for a 12-30 pound dog, anywhere between 3-5 years old - perfect in my mind.
