They are great pets and also keep unwanted guests away while we are gone.
We lost our last adult dane, Daisy at 13 years old last summer (our second dane). I bought my a wife a beautiful blue little girl a couple weeks later, much like yours pictured... a "band aide" pup. At 9 weeks old her little heart ruptured and she died instanty.
Wife has sworn off great danes after that experience.
Awesome family members IMO.
