By crate she means what I think you're thinking. ;) A cage or an airline type carrier. They're invaluable when you're housetraining and afterwards. I have 5 dogs and 3 crates that remain open...never an empty crate around here, someone always needs a break from something. :)
Purdue University did the study on the raised feeders. We've ALL heard just the opposite with them...until the study came out it was just accepted that they were better for the dog. There are some problems with the study, like any study, but it was basically accepted that raised feeders, at the very least, did nothing to prevent bloat if not raise the instance.
You can do a search for 'lupine collars' and you'll find tons of sites that sell them...even eBay typically has a decent selection. I love the patterns they come in. So far, they've all held up in the wash and with 5 dogs chewing on each other's necks...I've not had to take advantage of the lifetime guarantee! ;)
Another thing you may want to start going, not necessarily buying, is to research food a bit and see what you'll eventually want Earl to eat. There's a ton of information out there and you'll want to make an informed decision.
Most of all...store up all of your patience! ;) Have a great time with him...they aren't puppies for long!
