To all of you who gave the great advise, thank you! My husband and I just got a great dane puppy, 6 weeks old, and I've been wondering about many of these topics and how to make sure that we raise her to be a wonderful dog. I knew about the puppy classes due to my sisters dogs, but didn't know that petsmart offered them. I was concerned being in a new area about where to go for things like that. Thanks again for all the advise, I know that I hope to remember all of it, or at least as much as I can and hope to put it to good use!
