I'm with you as far as a pure-breed to a point. But be open minded, unless you are a die hard for a certain breed.

My Golden was freaking awesome, but he got cancer at 8 yo and broke my heart. He lasted 2 weeks after the diagnosis.

My "mutt" (lab mixed with ??) is 13 yo and going strong. He's an old man and doesn't chase the rabbits like he used to, but he's still going and the doc tells me that the mutts always last longer. Doc said he "looks great" a few months ago.

Just my 2 cents. Honestly, when my boy does go, I'll probably get another Golden or two. I just love them.

Either way, get a dog and love every minute you have with it!
