I just purchased my 2 & 3 Great Dane from this breeder. My first Great Dane "Fritz" lived to be almost 8, he passed away on Memorial Day of this year 2012.
Me, my wife and kids (now 10-11 years old). Missed him so much, 1 week later we bought a buster of a dog name Bullseye, and 3 weeks after that we bought a sweet little girl Dane named Jessie. The breeder let me, my wife, and kids into her house and we meet all the dogs 1 by 1. We even met my dogs Fritz's dad, who is now 10 1/2.
Unfortunately, not every dog, human, cat, etc., will be blessed with good health. I will back this breeder 100% all day long.
I hope in 7-9 years she is still in busy, because I will buy some more of her dogs. ;)
