Thanks for the replies, everyone!
I currently have a female chocolate lab, who is 5 years old. She weighs about 90 pounds, so I'm used to the bigness (I understand a dane will be considerably bigger.) We also have 3 cats and various other caged animals.
We have a large house, about 3000...
Anyone have any suggestions, advice, or anything else to share?
I've always wanted a dane, but haven't been around them much, so I don't know what to expect other than what I've read on the internet.
