I have a coworker who recently lost her dog to a heart attack. After grieving, she is looking for another. But there is a problem, she prefers a larger breed dog. She had a great dane - mastiff mix and would absolutely love another one. She lives in California on many acres of land, so the dog would have lots and lots of room to run and she and her family are very loving to there animals. I mean they even took in a one-eyed goose and a cat with half a tongue due to injury. If anyone knows of any information that I can give her about anyone selling or giving away a type of dog like this it would be so greatly appreciated.
