You were right about the eating. I had to hand feed him kibble to get him to eat. He adjusted fine to the apartment, but is really scared of outside (I posted a new thread concerning that.)Give him/her some time to sniff around and explore your home, it will help him to get comfortable in this new place (your home) faster
Don't be too concerned if he/she doesn't eat very much the first day home
Be consistent in everything you do! They will learn what is expected of them so much faster that way
Give him/her lots of love! And be ready to come back to DogForums with all the questions that are sure to pop up.
Also, try to give the puppy a little bit of alone time every day (in a crate or something similar).. Being with someone 24/7 can really contribute to the development of separation anxiety.. and that's -not- fun to deal with.
