I think that's what happened to me. The Scott County, KY, Humane Society got this really sweet black and white puppy with BIG paws and decided to foster him and adopt him out. They probably suspected he was part Pit but thought he might be part Dane instead and represented him as being part Dane. My problem is he gave his all to me and turned out to be a totally sweet dog by the time it became obvious he was a Pitador instead of a Daneador. Given what a wonderful character he was and is, I couldn't very well destroy his whole life just because of some human error. Now my big problem is keeping him from pushing me out of bed at night.
A friend of mine has a nice field Lab who is a regular Casanova. Nothing will keep him from the ladies - he goes out windows, over 8 foot fences, etc. etc. There are an awful lot of puppies in the neighborhood who look just like him . . . fortunately he's a good looking dog with a terrific temperament.
One of the downsides of the Danes is that they don't live long at all.
