chrismiss, I have three. My dogs were all adopted from shelters and all mixes. My first one is 13 and she's a fluffy lab mix. No one has really ever figured out exactly what she's mixed with.
Then I adopted two sisters almost a year ago. One is definitely a golden, and the other one looks like a grayhound? or something similar with shepard coloring.
My lab and golden are both very good dogs, very calm, relaxed, gentle and fun.
The other one is nervous, easily startled and has snapped at me once or twice. As long as things are quiet and calm in the house, she's happy, but she's going to be a little more difficult to deal with than the other two.
