Wow, thank you all for such great info! I agree about Standard poodles--our neighbor across the street had one when I was younger and it was a VERY smart and loyal dog.
I decided to give the BM a pass--he was a beautiful animal that looked like he could do anything he wanted, but he was SO work-focused he would have gone insane at our house. The good thing is, the people who were kenneling him for the trainer really wanted him and were working to come up with the money for him, so he will be in a good home.
jacarape, thanks so much for your info and beautiful pictures! It sounds like you are in an incredible situation. Enjoy every minute of it!
I went to Petco last weekend and they had the rescue dogs there. I had to stop to see who they brought, and they had the perfect dog. She is a Great Pyrenees/Lab mix and I had not paid attention to her on their Web site since I thought she would be a lot bigger than she actually is. She's the same height as Shadow, but about 10 lbs heavier (fed well at her foster home, but we're slowly working on that). She is about 1 to 2 years old and was rescued from the Little Rock shelter in December. She and Shadow get along very well, and she is definitely alert to anything going on around the yard, and barks to let me know.
Here's a few pictures for your enjoyment (she is the yellow & white one):
She is calm, sweet, wags her tail when she sees you and is a good, steady dog. The antithesis of Shadow (Mr. Boisterous)!
Her name is Sadie.
Thank you all again for the great help and information as we tried to find the right dog. This one looks wonderful, and she will have a good forever home with us.
