Olympia is one of the best dogs we have ever had and she was a shelter dog. Her previous owners had payed $3,000 for her and took her to the shelter because they kept her in a kennel outside all the time when they were at work. The neighbors kept complaining about her barking and she ended up in the shelter. She has champion bloodlines! She is the sweetest dog for us but when strangers come by they better not lay a hand on us. The last time I had her weighed at the vet's office she weighed in at 120. She is HUGE for a female and she isn't over weight. She is so tolerant of everything we put her through. She lives with cats and when I fostered we never had a problem with other dogs.
