We have had Seven for a year!
Seven is a pure-bred female rottweiler adopted from King County Animal Care & Control on June 10, 2008.
Here are a few pictures from her training class:

Seven intently paying attention to something off in the distance while on a "down."

Seven waiting to be released from a "sit" while we walk around her.

Still Waiting . . .

Break time.

More work. Seven has to "walk" with her shoulder right next to my hip.

Still working on off-leash commands.

Almost done with the class.
Next step, AKC Obedience trials? We'll see. Good dog, Seven.
